I have come across a problem doing a POST when going through a proxy.
The same operation works fine without the proxy. I'm trying to figure
out if it's an httpclient bug, or perhaps some HTTP protocol violation
on the site I'm going to. From the debug statements, it seems to me
that httpclient is sending all the headers first, then getting a
response including the proxy response. Then it sends the actual POST
parameters, but appears to not send the headers again. This request
times out, but using the browser works fine.
This was with version 3.0. I tried 3.0.1 and also 3.1-beta but same
results.
