When I set: ProxyErrorOverride On I'm seeing page load times increase from about 1-2 seconds, to nearly 20 seconds. I'm not seeing anything logged to the apache error log. I'm running Apache HTTPD 2.4.4 (built from source) on a RHEL6 server. This is configured as a reverse proxy, proxying via https to a tomcat server (using APR https connector). The only slightly non-standard module I have installed is mod_shibboleth (although that's not being used on this virtual host). If anyone has any ideas as to why this happening, or how I can debug this, hopefully leading to a way to use this without massively impacting performance I would be very grateful. Thanks, Paul |
