Alex, thank you for taking the time to help me. 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.
