Abstract

In a transmission system a proxy server (66) is located between a user terminal (52) and a server (70). The proxy server has means for intercepting and storing cookies transmitted from the server (70) to the user terminal (52). When a server (70) is contacted by a user terminal (52) and the server (70) transmits a cookie to the user terminal (52), the cookie is intercepted and stored in the proxy server (66). Information regarding the remote server, e.g. its URL and an identification identifying the user terminal (52) is stored together with the cookie. The next time the user terminal (52) accesses the same server (70) the proxy server (66) matches the requested URL and the identification information and in this manner finds the stored cookie. The cookie is then added to the request message so that the server (70) is accessed with a copy of the cookie as desired. In this manner the cookies do not need to be stored in the user terminal (52), which may have a small memory and which therefore is not suited for storing cookies. Furthermore, when the user terminal (52) is a mobile terminal the cookie is not transmitted over an air-interface, thereby reducing the risk of eavesdropping significantly.

Description

512 672 2 Typiskt använder servern cookien för att komma ihåg användaren och för att bibehålla illusionen av en session som sträcker sig över flera sidor. Eftersom en cookie inte är en del av standard- HTTP-specifikationen stödjer endast en del webläsare dessa, såsom "Microsoft Internet Explorer" 3,0 och högre och Netscape Navigator 2,0 och högre. Servern och/eller dess CGI-skript måste också ha kännedom om cookies för att kunna dra fördel av dem. 512 672 2 Typically, the server uses the cookie to remember the user and to maintain the illusion of a multi-page session. Because a cookie is not part of the standard HTTP specification, only some browsers support it, such as "Microsoft Internet Explorer" 3.0 and higher and Netscape Navigator 2.0 and higher. The server and / or its CGI scripts must also be aware of cookies in order to take advantage of them.

En cookie kan inte användas för att stjäla information om ett datorsystem, dvs den kan inte gå in i datorsystemet och återvända med information från det. De kan endast användas för att lagra information som inmatas vid något tillfälle. Således kan till exempel om någon fyller i ett formulär som anger en föredragen färg, servern omvandla denna information till en cookie och skicka denna till den webläsare som används. Nästa gång som webläsaren ansluter till webplatsen kommer weblåsaren att returnera cookien och därigenom möjliggöra för servern att ändra bakgrundsfärgen på sina sidor så att dessa passar användarens preferenser.A cookie cannot be used to steal information about a computer system, ie it cannot enter the computer system and return information from it. They can only be used to store information entered at any one time. Thus, for example, if someone fills in a form indicating a preferred color, the server may convert this information into a cookie and send it to the browser used. The next time the browser connects to the website, the browser will return the cookie and thereby enable the server to change the background color of its pages to suit the user's preferences.

Informationen som finns i dessa cookies kan emellertid snappas upp när den överförs på Internet. Detta ställer kanske inte till ett så stort problem när informationen överförs på ett fast nät eller när informationen är av okänslig natur, såsom färgpreferenser.However, the information contained in these cookies may be intercepted when transmitted over the Internet. This may not be such a big problem when the information is transmitted on a fixed network or when the information is of an insensitive nature, such as color preferences.

I några fall är informationen som finns i dessa cookies konfidentiell och ibland kan den också behöva överföras över ett trådlöst nät, till exempel när ändanvändaren använder en mobil terminal, såsom en laptop-dator eller någon annan dator som kommunicerar via modem över ett trådlöst nät. I sådana fall kan den konfidentiella informationen tämligen enkelt avlyssnas 5x 512 672 3 eftersom denna information, åtminstone delvis överförs över ett luftgrànssnitt där den kan uppsnappas av ett antal olika sorters utrustningar.In some cases, the information contained in these cookies is confidential and sometimes it may also need to be transmitted over a wireless network, for example when the end user uses a mobile terminal, such as a laptop computer or another computer that communicates via modem over a wireless network. In such cases, the confidential information can be fairly easily intercepted 5x 512 672 3 since this information is, at least in part, transmitted over an air interface where it can be intercepted by a number of different types of equipment.

Det finns dessutom ett problem som hör samman med överföringen av cookies från olika webplatser eftersom webplatsen inte kan bestämma om den använda terminal som cookies skall skickas till kan ta emot och spara cookies. Således är exempelvis i några handhàllna användarterminaler minnesutrymmet mycket begränsat och om många webplatser skickar cookies till en sådan användarterminal kommer minnet i en sådan terminal att ganska snabbt bli fullt med cookies och annan, mer viktig, information kan inte lagras.There is also a problem associated with the transfer of cookies from different websites because the website can not decide whether the used terminal to which cookies are to be sent can receive and save cookies. Thus, for example, in some handheld user terminals the memory space is very limited and if many websites send cookies to such a user terminal, the memory in such a terminal will quite quickly become full of cookies and other, more important, information can not be stored.

REDoGöRELsE FÖR UPPFINNINGEN Det är ett syfte med föreliggande uppfinning att övervinna problemen som hör samman med överföring av cookies till en användarterminal som har ett mycket begränsat minne och också att minska risken för att cookieinformation kan avlyssnas såsom beskrivits ovan.SUMMARY OF THE INVENTION It is an object of the present invention to overcome the problems associated with the transfer of cookies to a user terminal having a very limited memory and also to reduce the risk that cookie information may be intercepted as described above.

Detta syfte och andra uppnås genom att placera en proxyserver mellan en ändanvändare och en avlägsen server, vilken kan avläsa och lagra cookies som sänds från en avlägsen server till användarterminalen. w__”,_ ,_ _M s 1 Således kommer cookien att fångas upp och lagras i proxyservern när en på avstånd belägen HTTP-server eller liknande kontaktas av användarterminalen och den på avstånd liggande servern sänder É en cookie användarterminalen. Information avseende den på avstånd liggande servern, till exempel URL och en identitet som : 512 672 4 identifierar användarterminalen eller användaren lagras tillsammans med cookien. Nästa gång som användarterminalen eller användaren kontaktar samma HTTP-server matchar proxyservern den begärda URL:en och identifieringsinformationen och hittar på detta sätt den lagrade cookien. Cookien läggs sedan till meddelandet så att den på avstånd belägna servern kontaktas med en kopia av cookien såsom önskas.å På detta sätt behöver inte cookies lagras i användarterminalen vilken kan ha ett litet minne och därför inte är lämpad för att lagra cookies. Vidare överförs inte cookien över något luftgränssnitt då användarterminalen är en mobil terminal vilket därigenom signifikant minskar mängden data som överförs över luftgränssnittet.This purpose and others are achieved by placing a proxy server between an end user and a remote server, which can read and store cookies sent from a remote server to the user terminal. w __ ”, _, _ _M s 1 Thus, the cookie will be captured and stored in the proxy server when a remote HTTP server or similar is contacted by the user terminal and the remote server sends É a cookie to the user terminal. Information regarding the remote server, such as the URL and an identity that: 512 672 4 identifies the user terminal or the user is stored together with the cookie. The next time the user terminal or user contacts the same HTTP server, the proxy server matches the requested URL and identification information, thus finding the stored cookie. The cookie is then added to the message so that the remote server is contacted with a copy of the cookie as desired.å In this way, cookies do not need to be stored in the user terminal which may have a small memory and is therefore not suitable for storing cookies. Furthermore, the cookie is not transmitted over any air interface as the user terminal is a mobile terminal, which thereby significantly reduces the amount of data transmitted over the air interface.

KORTFATTAD BESKRIVNING AV RITNINGARNA Föreliggande uppfinning kommer nu att beskrivas närmare med hjälp av icke begränsande exempel och med hänvisning till de bilagda ritningarna, på vilka: - Fig. l är en allmän vy över ett transmissionssystem innefattande en mobil användarterminal.BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described in more detail by way of non-limiting example and with reference to the accompanying drawings, in which: Fig. 1 is a general view of a transmission system comprising a mobile user terminal.

- Fig. 2 är ett flödesschema som visar stegen som utförs i en proxyserver vid mottagande av en URL-begäran från en användarterminal.Fig. 2 is a flow chart showing the steps performed in a proxy server upon receipt of a URL request from a user terminal.

BESKRIVNING AV FÖREDRAGNA UTFÖRINGSFORMR I fig. 1 visas en allmän vy över ett kommunikationsnät. Nätet innefattar en användarterminal 52 med en webläsare 54.DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 shows a general view of a communication network. The network includes a user terminal 52 with a web browser 54.

Användarterminalen 52 innefattar också ett trådlöst modem 58 med hjälp av vilket användarterminalen 52 kan ansluta till en radiobasstation 60. Radiobasstationen 60 är ansluten till en avlägsen proxyserver 66 vilken företrädesvis är placerad på ett 512 672 centralt ställe i transmissionssystemet, exempelvis Home Location Register (HLR) om systemet är ett GSM-system.The user terminal 52 also includes a wireless modem 58 by means of which the user terminal 52 can connect to a radio base station 60. The radio base station 60 is connected to a remote proxy server 66 which is preferably located at a central location in the transmission system, such as the Home Location Register (CPR). if the system is a GSM system.

Proxyservern 66 innefattar eller är ansluten till ett minne 72 för att lagra information avseende cookies som överförs via proxyservern 66. Proxyservern 66 är ansluten till World Wide Web (WWW) eller till Internet 68 till vilket ett antal andra servrar 70 är anslutna.The proxy server 66 includes or is connected to a memory 72 for storing information regarding cookies transmitted via the proxy server 66. The proxy server 66 is connected to the World Wide Web (WWW) or to the Internet 68 to which a number of other servers 70 are connected.

Proxyservern 66 kan också vara placerad på något annat ställe i systemet eller distribueras över systemet. Exempelvis kan om transmissionssystemet är ett GSM-system cookie-informationen lagras vid “visiting Location Register" (VLR)eller t.o.m vara placerad pà samma ställe som radiobasstationen.The proxy server 66 may also be located elsewhere in the system or distributed throughout the system. For example, if the transmission system is a GSM system, the cookie information may be stored at the "Visiting Location Register" (VLR) or even be located in the same place as the radio base station.

I en föredragen utföringsform för ett GSM-system är proxyservern 66 placerad tillsammans med HLR:en och VLR:en och eventuellt är också några av radiobasstationerna försedda med cache-servrar för att cacha cookieinformation. Liknande arrangemang kan naturligtvis också göras för andra cellulära radiosystem.In a preferred embodiment of a GSM system, the proxy server 66 is located together with the CPR and the VLR and possibly some of the radio base stations are also provided with cache servers for caching cookie information. Similar arrangements can of course also be made for other cellular radio systems.

När användarterminalen 52 kontaktar en webplats för första gången i en sådan på avstånd belägen server 70 kan en cookie överföras tillbaka mot användarterminalen 52. Såsom beskrivits ovan är en cookie en liten bit information, ofta inte mer än en kort sessionsidentifikation, som HTTP-servern sänder till webläsaren och som kan bestå av upp till 4 kbyte information.When the user terminal 52 contacts a website for the first time in such a remote server 70, a cookie can be transferred back to the user terminal 52. As described above, a cookie is a small piece of information, often no more than a short session identification, which the HTTP server sends to the browser and which can consist of up to 4 kbytes of information.

Cookien fångas upp av proxyservern 66, vilken lagrar cookien tillsammans med information avseende URL:en som har utfärdat cookien och en identifiering som identifierar användarterminalen 52. Cookien behöver då inte överföras över det trådlösa nätet vilket vanligen har en mycket liten bandbredd, typiskt 4,8 512 672 6 kbit/s, vilket kommer att minska överföringstiden. Dessutom behöver inte cookien lagras i användarterminalen 52, vilken kan vara en handhållen dator såsom MC-16 tillverkad av företaget Ericsson, eller en "smart-phone", vilken kan ha ett mycket begränsat minne.The cookie is captured by the proxy server 66, which stores the cookie together with information regarding the URL that issued the cookie and an identification identifying the user terminal 52. The cookie then does not need to be transmitted over the wireless network which usually has a very small bandwidth, typically 4.8 512 672 6 kbit / s, which will reduce the transmission time. In addition, the cookie does not need to be stored in the user terminal 52, which may be a handheld computer such as the MC-16 manufactured by the company Ericsson, or a "smart-phone", which may have a very limited memory.

Nästa gång som användarterminalen 52 ansluter till samma webplats som har utfärdat cookien kommer proxyservern 66 att identifiera användarterminalen 52 och kontrollera vilken webplats eller URL (Uniform Resource Locator) som användaren kontaktar. Om webplatsen har kontaktats tidigare kommer proxyservern att kunna matcha identiteten med URL:en och därigenom hitta cookien som är associerad med denna särskilda URL.The next time the user terminal 52 connects to the same website that issued the cookie, the proxy server 66 will identify the user terminal 52 and check which website or URL (Uniform Resource Locator) the user is contacting. If the website has been contacted before, the proxy server will be able to match the identity with the URL and thereby find the cookie associated with this particular URL.

Proxyservern 66 lägger sedan till cookien till begäran från användarterminalen 52 till servern 70. Den på avstånd belägna servern 70 kommer då att mottaga en anslutningsbegäran tillsammans med en cookie som om cookien hade returnerats från själva webläsaren. På detta sätt minskas datatrafiken över den trådlösa, låghastighetsdelen av accessvägen och minnesbehovet i användarterminalen 52 kan minskas.The proxy server 66 then adds the cookie to the request from the user terminal 52 to the server 70. The remote server 70 will then receive a connection request along with a cookie as if the cookie had been returned from the browser itself. In this way, the data traffic over the wireless is reduced, the low-speed part of the access path and the memory requirement in the user terminal 52 can be reduced.

I fig. 2 visas ett flödesschema över de operationer som utförs i proxyservrarna då en anslutningsbegäran mottages från användarterminalen mot en på avstånd liggande server 70 ansluten till Internet. Således mottages först i ett block 201 begäran från användarterminalen 52. Därefter läses i ett block 203 den URL som användarterminalen vill ansluta till från begäran. Sedan bestäms i ett block 205 identiteten på terminalen eller användaren. 512 672 7 Resultatet av operationerna som utförs i blocken 203 och 205 används sedan i ett block 207 för att bestämma om URL:en tidigare har begärts eller besökts av denna särskilda användarterminal. Således kontrolleras i blocket 207 om en cookie finns lagrad i minnet 72 vilken är associerad med denna särskilda URL och denna särskilda identitet.Fig. 2 shows a flow chart of the operations performed in the proxy servers when a connection request is received from the user terminal to a remote server 70 connected to the Internet. Thus, in a block 201, a request is first received from the user terminal 52. Then, in a block 203, the URL to which the user terminal wants to connect is read from the request. Then, in a block 205, the identity of the terminal or user is determined. The result of the operations performed in blocks 203 and 205 is then used in a block 207 to determine if the URL has previously been requested or visited by this particular user terminal. Thus, in block 207, it is checked if a cookie is stored in the memory 72 which is associated with this particular URL and this particular identity.

Om dessa matchar varandra, dvs servern tidigare har lagrat en cookie för denna särskilda användare som svarar mot denna särskilda URL, läggs cookien till begäran i ett block 209 och begäran vidarebefordras sedan mot den på avstånd liggande servern under vilken den begärda URL:en finns. Om, å andra sidan, någon matchning inte kan utföras i blocket 207, dvs att denna särskilda URL ansluts till för första gången av denna särskilda användare, så vidarebefordras begäran direkt mot servern 70 i blocket 211.If these match each other, ie the server has previously stored a cookie for this particular user corresponding to this particular URL, the cookie is added to the request in a block 209 and the request is then forwarded to the remote server under which the requested URL is located. If, on the other hand, no matching can be performed in block 207, i.e. that this particular URL is connected to for the first time by this particular user, then the request is forwarded directly to the server 70 in block 211.

Således behöver cookien inte lagras i användarterminalen genom att lagra cookie-information i en proxyserver, vilka användarterminaler i många fall har ett litet minne och därför inte är lämpade att lagra cookies. Vidare överförs inte cookien över ett luftgränssnitt då användarterminalen är mobil terminal, vilket signifikant minskar mängden data som överförs.Thus, the cookie does not need to be stored in the user terminal by storing cookie information in a proxy server, which user terminals in many cases have a small memory and are therefore not suitable for storing cookies. Furthermore, the cookie is not transmitted over an air interface as the user terminal is a mobile terminal, which significantly reduces the amount of data transmitted.
