Subject RE: mod_proxy and original http headers
Date Tue, 11 Jun 2002 18:11:57 GMT
I think my problem is that http headers from the proxied request are showing
up in the html after Apache returns the content.  I'm pretty sure that
Apache is giving its own headers, so I'm not sure what is going on.

Here is one of my previous posts:

Hi, all.

I'm having my problem again.  

I am using Stronghold on Solaris to proxy content from port 80 on a machine
(Search engine), to port 443 on the same machine.  I do this to provide
authentication and encryption.  

When I use a simply mod_proxy request to proxy the content, like so:

ProxyPass / http://some.IP/
ProxyPassReverse / http://some.IP/

All of my content gets jumbled, here is a copy of the html after it is
jumbled:

<snip>
</div>
</body>

</html>

HTTP/1.0 200 OK
Server: Ultraseek/3.1 Python/1.5.1
Date: Mon, 10 Jun 2002 12:42:40 GMT
Content-type: text/html
Content-length: 11608

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html>
</snip

Notice how the ending html tag comes before the content headers.

I changed the configuration to use mod_rewrite, and for a while, it didn't
have the same issue (a few hours, at least),
but now it does.  Here is my config:

RewriteRule ^(.*)$ http://some.IP$1 [proxy]
ProxyRequests   on
NoCache         *
ProxyPassReverse / http://some.IP/

I have contacted my vendor, but have not been able to reach a solution.  

I would appreciate any and all help in this matter.  This seems like a
serious enough issue as to warrant some attention from someone.

Version information:
 Stronghold/3.0 Apache/1.3.12 C2NetEU/3012 (Unix) PHP/3.0.16 mod_ssl/2.6.4
OpenSSL/0.9.5a mod_perl/1.22 configured
