An individual that is using the proxy requires the HTTP_KEEP_ALIVE header as a script that worked with another proxy server is now not working. The only apparent difference is the lack of the HTTP_KEEP_ALIVE header. So, basically the individual is claiming the lack of the HTTP_KEEP_ALIVE header is preventing the script from working properly. Thanks for the help.
