Any ideas?

I have several ideas.

I work for a company that makes transparent proxy software. Microsoft's proxy products don't behave in the manner that other proxies do. When we have issues with our proxy breaking things, we sniff the network and watch the request come though. Some proxies are extremely sensitive to HTTP requests, and require special formatting of HTTP headers to work correctly. For instance, here's a typical HTTP request from an average program:

GET www.google.com/index.html HTTP/1.0
[download]

This code will fail on most proxies because proxies require an additional header. So the following request will work on most proxies:

GET /index.html HTTP/1.0
Host: www.google.com
[download]

Now this works on virtually every proxy. Except WinProxy. WinProxy requires an additional header, as well as browser identification, so the same request would look like this:

GET / HTTP/1.0
Host: www.google.com
User-agent: Mozilla/4.7 
Remote-Host-Wp: 10.0.3.82
[download]

Aparently the session management part of WinProxy is severely lacking.

So the point to all of this is that writing to WinProxy is extremely difficult (do a query for "WinProxy" in Mozilla's bug tracking database, and see how WinProxy breaks everything). My suggestion is to sniff the request, figure out where the proxy is dying, and use LWP::UserAgent to fake the headers WinProxy requires.

Sorry for the rant :-)

No batteries included, no strings attached, your mileage may vary.

Since I'm playing with and trying to learn these type of things, do the extra headers have any side effects in the proxies that don't require them?

Also, I notice that you're using HTTP 1.0, instead of 1.1. Is this significant?

Any ideas or explanation first why it won't work as is through the Proxy?

He means use the CGI.pm module, available from CPAN or quite likely already installed on your system. You're basically re-inventing CGI parameter parsing, which is essentially already mastered in this CGI module. By using the module to do your parsing instead of re-implementing it yourself, we can essentially rule out that part of your code as the problem.
