I'm having CGI redirect problems mp2 (cvs).
Instead of being redirected to the proper web page, I'm sometimes getting a "302 Moved" page containing a link to the correct URL.
Damn this was a hard bug to track down.
The cause of the problem was my perl code calling flush.pl and flushing STDOUT at a point prior to it printing the response headers. Under mp2, flushing STDOUT calls mpxs_output_flush in xs/Apache/RequestIO/Apache__RequestIO.h, which in turn calls ap_rflush, which triggers creation of the HTTP header, which at this stage, prior to my script printing its 302 header, uses a 200 OK status. So instead of a proper redirect being sent back to the browser, a normal web page with an embedded 302 link is sent.
Everything seems to work if the ap_rflush call is removed from mpxs_output_flush, but I don't know if this is the proper way to fix it.
