Hello, Using mod_proxy in reverse mode with ProxyErrorOverride enabled, and a persistent back-end connection causes any server response of 304 to hang until the KeepAliveTimeOut expires. This has been tested on Apache 2.0.44, running on Linux-x86.
Maybe mod_proxy becomes confused when ProxyErrorOverride is used with persistent connections in that it's expecting a response body on a 304. Bug 17928 was opened by my colleague to track this issue. Thanks, Graham Wiseman [EMAIL PROTECTED]
