Describe the problem to be solved

Hello,
first of all, thank you very much for this great project. I like to use this project in different situations. I would like to ask if it would be possible to extend the tool with the following feature:

I am interested in more usecases for simple static-pages which from my ops point of view could run best directly integrated in the "defaultbackend" so this tool.

Currently I am establishing the /.well-known/security.txt on the loadbalancers. See background. This is a static TXT which I would like to read via configmap or similar.

Why here? Because I like the logging, the lightweight implementation and the deployment without filesystem-access.

Suggest a solution

The way of request-handling could be triggered via 'static-path' or better a request header Static-Page: foobar (e.g. set by the loadbalancer).
maybe also an ENV variable with a comma separated list of static pages as path or header-value (value=filename) to include.

Additional context

I'm not sure if this is beyond the scope of this tool from your point of view, I think it would be a good extension.
Would there be interest in such a feature?
kind regards
