Squid does not forward the Keep-Alive header because Squid considers it a hop-by-hop header. Per HTTP protocol, hop-by-hop headers are not forwarded by proxies. When a client sends Keep-Alive to a proxy, the header is for the proxy and not for the origin server; it only applies to the connection that ends at the proxy. FWIW, the header itself is outdated and probably not supported by many HTTP agents. Squid itself uses a Connection header to signal HTTP connection persistence. The Connection is also a hop-by-hop header, naturally. It may help if you explain why you want to see that header sent to the script. What are you trying to accomplish or check? HTH, Alex.
