500 usually means that the request caused apache to execute some server-sided code (eg CGI or PHP) but that the program failed. So this will be an error in the program apache called - not in apache itself or in any proxy. > There is no info in error.log file that > helps me find out what went wrong. Are you absolutely sure? Every error in apache (4xx or 5xx response code) should lead to a line in the error log.. please check again (cross-reference the timestamps) Are you sure you don't get "Premature end of script headers"? > I was wondering how else I can get more info why the request > failed. It depends on the server-sided logic - if it's CGI, you can get the script output by activating ScriptLog (see docs for details). > I am sure the request doesn't get reverse proxied to > the destination web server and something happens inside Apache. This is correct.. But I'm wondering why a dynamic resource would end up getting proxied - usually, you proxy requests immediately (based on the pattern of the URL). Can you supply more details of exactly how your site works?
