I understand that the keep-alive header is not suppose to be forwarded
but is there any way to send custom headers as Alex recommended? So
basically I want Squid to automatically send HTTP_KEEP_ALIVE = 300
even if its not getting that information from the client or the
server. The header just has to be there. Is that possible?

Thanks in advance.
