The long story... I am calling mapserv (http://mapserver.org) as a cgi program from OpenLayers (http://openlayers.org).

Description John Lightsey 2009-10-21 16:35:38 UTC Noticed this with Apache 2.0.63, but it looks fairly clear that the same problem exists in 2.2.14. The way proxy_httpd.c is written, if a keepalive connection is closed by the other side in ap_proxy_http_handler() after ap_proxy_http_create_connection() and before a response is received, Apache will consider this to be a connection error and generate a 502 response. This logic is only valid on the first request across the keepalive. According to the HTTP 1.1 spec, proxy_httpd.c must be capable of handling asynchronous close events in the middle of a keepalive session. When it encounters an unexpected close it should attempt to reestablish the connection and resend the request before generating a 502 response. Comment 1 Ruediger Pluem 2012-08-10 06:39:44 UTC Please check a recent 2.2.x / 2.4.x. This should have the problem fixed. Comment 2 William

This avoidsthe "proxy: error reading status line from remote server" error messagecaused by the race condition that the backend server closed the pooledconnection after the connection check by the proxy and before data sent bythe proxy reached the backend.
