My program connects to a proxy server (''the proxomitron'' in this case) and uses a loop that reads all available data when an event in signalled. Now it works most of the time but every time I download a large file it just STOPS 90% of the way then disconnects a few seconds later. Anyone have any ideas about this behavior? Any special settings or bugfixes that I don''t know about? Maybe its the proxomitron''s fault, is there a simple free HTTP proxy I can use?

Apache has HTTP/FTP proxying functionality in mod_proxy. Its "free", although "simple" may be stretching a bit.
