Is there a way to serve a webpage from a locally running tcp server listening on a unix domain socket instead of localhost:<port>?
something like:
file:///tmp/webpage.sock
my only real motivation is to avoid port conflicts in the 2000-5000 range.
It is easy to serve it.
But harder to get the client to use it.
However because you told me why you are doing it, I have another solution.
You want several web-servers to serve to only the local machine, but not have conflicts of port. It may also be nice if they all used the same port number.
Loopback addresses are 127.0.0.0/8 That is 127.x.x.x not just 127.0.0.1.
Therefore use a different IP address for each server. E.g. 127.0.0.2, 127.0.0.3 ...
ssh can do it but there is overhead of encryption. Both would need the server to listen on a socket, and would just forward from another unix socket. I think I did it once. But could not convince the browser to use it. I would ask another question. But be clear about what you are not asking for, and link to this question.
