I was wondering, has anyone built a FIltering Forward Proxy Server using
ooRexx on Windows?
I hope I have my terminology correct. I want a script running on a
machine. That machine is declared as the default gateway for other
machines on the LAN.
HTTP requests to that machine are examined for url white/black lists and if
they pass are forwarded to the 'real' gateway. If not some other action is
taken.
I think it should not be too hard to do, but I'm a bit unclear.
I have the single thread server code that Mike demonstrated at his wiki
presentation a few years back and I have in the past successfully adapted
it to serve my own pages on the LAN.
I'm not sure about how the server machine would then talk to the 'real'
gateway.
Using rexxCurl perhaps?
I know that it is possible to do this with 3rd party apps., but I'm curious
whether it would be possible to create something lightweight to do this
using ooRexx.
I'm also a little unsure about the single threaded nature of the Server and
what effect that would have on concurrent users.
On another note when Howard was interested in promoting Rexx, we were
always on the lookout for useful applications that were straightforward to
build in Rexx for magazine articles. It occurs to me that if we could do
this and do it well, this might be one such application, though I fear the
socket function use may be a bit obscure for an article.
thanks for listening
