Re: [PLUG] Apache Mod Proxy & Mod Rewrite Questions

[Casey Bralla <MailList@nerdworld.org>]

Jason, thanks for your comments.  I tried this:

<VirtualHost *>
    ServerName www.oldsite.org
    RewriteEngine On
    ProxyPreserveHost On
    # Send all inquiries for oldsite.com to newsite.com
    RewriteRule ^/(.*)$ http://www.newsite.com/$1 [P,L]
</VirtualHost>

To my thinking, this should have worked.

Unfortunately, I still get an "Internal Server Error" and the (to me) 
unfathomable error message in /var/log/apache2/error.log


I had put these items in my sites-available directory.   I also tried putting 
them in /etc/apache2/mods-available/proxy.conf

I moved the rewrite lines to there, and now I get a "Not Found" error, and the 
error logs complain about /htdocs not being found.   This seems better, but 
I'm still kinda lost.


Any other suggestions?
