Hi, Can you tell if the OS Keep-alive feature should be expected to work on forward proxy?
The mod_proxy of latest httpd 2.2 and trunk (2.3) has OS Keep-alive (Keep-alive connection to origin server) feature, but it seems not working when we configure the httpd as the forward proxy server. If the client connection is kept alive, the proxy sends indeed "Connection: Keep-alive" to the origin server but the proxy doesn't actually try to keep the OS connection alive; it closes the OS connection immediately after receiving the response. The inconsistency between sending "Connection: Keep-alive" and immediate connection closing looks like a defect (and I've just posted a bug report 49699). But apart from the inconsistency, I wonder if the OS Keep-alive of mod_proxy is designed to work for the forward proxy in the first place. Regards, Ryujiro Shibuya
