htaccess rewriterule for aliasses

Question

On our main domain we are running a CMS which feeds several domains with different input. The domains are directed with A records to the main ip address. The htaccess works fine it will bring up the right pages if you type in a url, lets say www.ictzorg.nl It will show the url www.ictzorg.nl in your browser which is originally www.ckc-seminars.nl/Event/ictzorg/2013/NL

This is the htaccess code

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?ictzorg.nl$
RewriteRule ^(.*)$ http://www.ckc-seminars.nl/Event/ictzorg/2013/NL/$1 [P]

Problem now is that if you click on a link on that page it will search for

www.ictzorg.nl/Event/ictzorg/2013/NL/Page/450

It should direct to

www.ckc-seminars.nl/Event/ictzorg/2013/NL/Page/450

and should be shown in the URL bar as

www.ictzorg.nl/Page/450

Answer 1

The rewrite rule you've written modifies both the domain, and the path, but you haven't updated the path in your page source.

You change ictzorg.nl to http://www.ckc-seminars.nl/Event/ictzorg/2013/NL/. Fine, that works.

But the link in the page source is: /Event/ictzorg/2013/NL/Page/451.

As it's a relative link, www.ictzorg.nl (the current domain in the browser) gets added to the front of it.

When it's clicked on, your rewrite rule then converts the www.ictzorg.nl to http://www.ckc-seminars.nl/Event/ictzorg/2013/NL/ again.

So the final url ends up having part repeated, like: http://www.ckc-seminars.nl/Event/ictzorg/2013/NL/Event/ictzorg/2013/NL/Page/451

Solution: get rid of the /Event/ictzorg/2013/NL/ at the start of each URL in the source of the page (or with an extra rewrite rule), because your rewrite rule will put it back.
