Description Vincent Jong 2005-12-16 19:48:45 UTC 
Platform: x86
OS: RedHat 7.3

Did a fresh install of Apache 2.2.0 and when accessing a cgi script that, let's 
say doesn't have the correct permissions, a 500 error page is correctly 
generated. The problem is that this page is displayed as HTML mark up with the 
extra added line of:

Additionally, a 500 Internal Server Error
error was encountered while trying to use an ErrorDocument to handle the
request.

This behavior was confirmed by Joshua Slive from the users@httpd mailing list 
under the thread entitled "500 Internal Server Error pages being rendered as 
markup". Joshua then found something similar where a patch was issued from
http://issues.apache.org/bugzilla/show_bug.cgi?id=36090

I've applied the patch, reconfigured, recompiled, and reinstalled Apache 2.2.0 
and the problem still persists.

I've taken a screenshot of the displayed page, and although this screenshot is a 
more recent screenshot where I've added server tokens to httpd.conf, this would 
be seen even with a default httpd.config file.

Thanks,

Vincent J.

I can repo this on production machines.  At a guess I think we aren't merging
the error headers correctly.... It seems to only happen with CGIs.

Worth noting here: this could've been opened by the fix to PR#36090

I too am experiencing this.

SUSE LINUX 10.1 (i586)

Apache/2.2.3 (Unix) DAV/2 Server

Confirmed this problem when configured with default options.

Attempting to access http://localhost/cgi-bin/printenv results in the error, as
expected because CGI has not been enabled yet.

The error page is in HTML source... unrendered.

This is going to be a problem with my web developers.  It is not expected behavior.

Paul Querna has opened a bug that is the actual cause for this issue. Closing
this one as a duplicate of that bug.
