I have mod_rewrite enabled and I am currently using it so that my forums and threads have .html exensions i.e. to redirect to the real php pages.

Hi, I am new to your forum, but if I understand your query correctly,
I think you can try the following:

Here goes....

Providing that your DNS is correctly pointed and both url's point to the same server, you need to add the following to httpd.conf


#
# UseCanonicalName: Determines how Apache constructs self-referencing
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client. When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

NameVirtualHost *:80 # if it doesnt exist already
and then in the Virtualhost Container

<VirtualHost *:80>
ServerName www.somedomain.com
ServerAlias somedomain.com
## Some other stuff
</VirtualHost>

This will tell Apache to redirect all requests to any of the above url's to the specified virtual host.

Hope it helps...

I'm not sure if this was said already, but I'll tell you anyways.

You can add "Redirect 301 /index.php http://www.daniweb.com" (without the quotes) to a .htaccess file within your /www or /public_html folder.

Hope this helps.
