Webmasters Stack Exchange is a question and answer site for pro webmasters. It's 100% free, no registration required.

I apologize ahead of time that this might be a common question, however I've spent 3-4 hours already on solutions which don't quite fix the problem.

I have a site and it is moving to a different domain, the problem is--the site is paired with software which looks for: http://site/version. Using a simple 301 redirect won't work because it'll get '301 Moved Permanently' instead of the actual data. So I thought.. ok--I made version.php which has:

<? echo file_get_contents('http://newsite/version'); ?>

So the idea is simple: When one requests http://site/version, give them http://site/version.php, else: redirect everything to http://newsite/$1

What I got was something like this:

RewriteEngine On
RewriteBase /
RewriteRule ^/version$ /version.php
RewriteCond %{HTTP_HOST} site\.com$ [NC]
RewriteCond %{REQUEST_URI} !^version$
RewriteRule ^(.*)$$1 [R=301]

I am no master at mod_rewrite rules, this is just what I hacked together and it doesn't work or I wouldn't be here. If someone who knows them better than I can help, I'd be very grateful. Thank you in advance.

I assume both site and newsite are hosted at the same place - one is a parked domain on the other? – w3d Aug 31 '13 at 22:30
that is not the case, they are completely different locations. – u8sand Aug 31 '13 at 23:08
In that case (unless there are other hosts/domains involved) then you don't need to check against %{HTTP_HOST}, since it will always be, and these RewriteCond directives can be removed. – w3d Aug 31 '13 at 23:56

I think you have the correct idea, but the directory prefix (/) is probably the main thing that is causing problems. Try the following...

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^site\.com$ [NC]
RewriteRule ^version$ /version.php [L]

RewriteCond %{HTTP_HOST} ^site\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/version
RewriteRule (.*)$1 [R=301,L]

The RewriteRule pattern in per-directory .htaccess files is matched against the URL less the directory prefix (ie. version, not /version), so your pattern would never match.

Conversely the REQUEST_URI variable always includes the full URI, including the directory prefix (/). And in this case, it is likely to be the rewritten URL, ie. /version.php and not /version. Although I simply removed the end-of-string placeholder ($) so it will catch both anyway - assuming you don't have other URLs that start "/version"?

EDIT: Note that if and are completely separate sites (as suggested in comments) and no other domains are parked at then you don't need to check the %{HTTP_HOST} and these RewriteCond directives can be removed.

This worked out perfectly. Thank you very much for your help as well as your explanation. I do not have any other url's prefixed with version but if that does happen I can simply do ^version(|.php)$ – u8sand Aug 31 '13 at 23:16
Yes, although it is probably preferable to write that as ^/version(\.php)?$ to make the ".php" optional and remember to escape the . in the regex. To be honest, I'm pretty sure you can just replace this with ^/version\.php$ (the rewritten URL), providing your directives remain in the same order as above. – w3d Sep 1 '13 at 0:02
