site_url removes part of string

[eluser]doors[/eluser]
I have something like this for my site_url in the config file:

http://www.example.com/catalog/

When I am using site_url function it gives the following string:

http://www.example.com

Why is that happening?

[eluser]Pygon[/eluser]
site_url is based off $config['base_url'] and doesn't contain any logic to strip anything off of it.

I think doors means somthing else.
site_url gives the url defined like Pygon said.
If you want it to point to something else try:

Code:

site_url('catelog');

Sorry guys. I was using base_url() instead of site_url().
