[Test Case] Setup Apache 2.4.7 * mod_rewrite * mod_ajp * mod_dir
Tomcat * Listening on Port 9001 Apache with a .htaccess in the example.net VirtualHost RewriteEngine On RewriteRule ^(.*)$ ajp://localhost:9001/$1 [P] Expected: Return from Tomcat HTTP Status 404 - / Reality: Return from Tomcat HTTP Status 404 - /index.html Workaround for this particular setup was to either disable mod_dir or disable DirectoryIndex in .htaccess. Or on VirtualHost context use ProxyPass. ProxyPass / ajp://localhost:9001/ ProxyPassReverse / ajp://localhost:9001/ [Impact] With DirectoryIndex disabled: <pre> [Thu Apr 30 13:55:18.761066 2015] [rewrite:trace3] [pid 31422] mod_rewrite.c(468): [client XXX.XXX.XXX.XXX:38052] XXX.XXX.XXX.XXX -
