Not AFAIK, but we have very specific plans to do exactly this in GNUnet
this year --- except that we'll be rewriting the result from libcurl as
it passes the reverse proxy and only go to one particular HTTP server
instead of different targets.

So I fully believe this is possible.   The main "mess" is that you will
have to write special logic for each HTTP method (PUT, POST, etc.) and
convert the inputs and outputs from MHD to CURL and back.  If you just
care about "GET", this should not take much.  If you want to also
support PUT and POST, I expect it to be a bit bigger.

If you are doing a free software implementation of such a reverse proxy,
I might be interested in the code ;-).


Happy hacking!
