htaccess rewrite breaks relative paths

Question

Hi,

I have an htaccess file which maps

http://www.myserver.com/home/

to

http://www.myserver.com/index.php?section=home

This part works fine. The issue I am facing now is, all my images and css reside in a sub-folder named assets, i.e.

http://www.myserver.com/assets/images/

http://www.myserver.com/assets/css/

etc.

After redirection the browser will look for the files under

http://www.myserver.com/home/assets/images/

which causes things to break, as this is not a valid path.

I have been able to add another rewrite that maps the above to the correct sub-folder, however, Firebug shows that the images are residing in:

http://www.myserver.com/home/assets/images/

I know it's not really a problem, after all, my images and css are loading just fine with this rule. I'm just curious as to how I could make the path shown to be the actual path, which is:

http://www.myserver.com/assets/images/

Pasting my htaccess file below. Thank you very much beforehand.

The problem is that you didn’t consider that relative URLs are resolved on the base URI that is the URI of the HTML document the reference is used in. So a relative URI path like assets/images/ in an HTML document with the URI path /home/ is resolved to /home/assets/images/ instead of /assets/images/.

You cannot change this with mod_rewrite as URI resolution is done by the client and not by the server. The only solutions are:

• change the base URI using the BASE element (note that this affects all relative URI);
• using absolute URI paths, e.g. /assets/images/ instead of a relative assets/images/;
• adjusting the relative URI path, so references in /home/ are adjusted to ../assets/images/ to reflect the path depth.
