Apache rewrite with many slash not working?

Question

I have modified a website with a redirection to a single page:

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

It works as it suppose to be. Everything is redirected to index.php. Here is a working example that display index.php with all images and css:

http://.....com/section1

The problem occur when I try :

http://....com/section1/subsection

The page is redirected to index.php, BUT no images, no css, no javascript. Inside the PHP script everything is like this directly linked to the images or css or javascript like:

<img src="images/images1.png> ... <img src="images2.png">

Why does url with many slash like .com../123/123/whatever does not work with images, css or javascript when .com/no_slash_url works?

Answer 1

You're rewriting without redirection, so the client thinks it's at the original unrewritten URL and all relative paths will be resolved relative to that URL. You should be able to work around this using the <base> element:

<base href="http://myserver.com" />

Let me try and clarify this with an example. If I have a page at http://mysite.com/index.php and all its images are at http://mysite.com/images/, my images might be referenced with a relative url like images/myImg.png. The client translates this url using the current path in the address bar. Now if I rewrite my URLs so that they look like http://mysite.com/mycategory/myarticle, any relative images would resolve to http://mysite.com/mycategory/myimages/, which is incorrect. By adding the base tag:

<base href="http://mysite.com" />

Each browser will now resolve the images relative to that path instead, correctly looking for http://mysite.com/images/.

Answer 2

Take a look at the html base tag

<base href="http://www.mysite.com/" />
