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.

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"?

It depends on the server-sided logic - if it's CGI, you can get the
script output by activating ScriptLog (see docs for details).=20

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?
