Apache rewrite

[localzuk]

Can anyone explain to me how to use Mod Rewrite in Apache 2 to do the following?

 

I want to rewrite any mention of 'servername' with 'differentservername'.

 

So basically, if the site has an absolute link http://servername/blah.jpg it should instead return http://differentservername/blah.jpg

You could use a redirect. I had to do a similar thing for our Apache server when we changed our domain name and it works how you describe.

 

ServerName servername
Redirect permanent / http://differentservername/

That isn't any use to us - it is reverse proxied so the server is not internet facing.

 

I'm looking at ProxyHTMLURLMap at the moment, using mod_proxy_html.

I'll explain my issue further - on this site, rather than use relative urls in the CSS 'style' code, they've used full server domains - eg:

 

[/font][font=monospace]background-image:url(http://server/icons/spacer.gif)[/font]

 

Rather than the more elegant way of doing it:

 

background-image:url(/sysicons/spacer.gif?bg=1)

 

So, the way I was thinking I should do it would be:

 

ProxyPass / http://server/
       
               ProxyPassReverse http://server/
               SetOutputFilter proxy-html
               ProxyHTMLURLMap http://server/ /
       

 

But it doesn't seem to be rewriting...

Would this work?

 

Redirect 301 http://servername/blah.jpg http://differentservername/blah.jpg

[localzuk]

Would this work?

 

Redirect 301 http://servername/blah.jpg http://differentservername/blah.jpg

 

No. That wouldn't rewrite anything - it'd just redirect any requests to the server for http://servername to http://differentservername - but as I said, differentservername is not an internet facing server - it is being reverse proxied.

I got it working by changing some other settings instead.
