Let's dive into a fresh perspective on a question I previously raised:
I've crafted a mod_rewrite snippet that checks for the existence of JavaScript, CSS, and PHP files on the subdomain they are called from (e.g., subdomain.example.com). If these files don't exist, Apache "redirects" to common.example.com, where common JS, CSS, and PHP files reside. Here is the code snippet:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)\.(js|css|php)$ http://common.example.com/$1.%2 [L]
This setup functions as intended when:
- You manually input the file name in the address bar.
- The JS or CSS files are referenced in the HTML markup.
However, it encounters issues when:
- The URL is utilized within a PHP or JS file (e.g., during an AJAX call), leading to a reference back to the subdomain hosting the HTML page (i.e., mod_rewrite fails to catch it):
subdomain.example.com
Thank you to the community for your assistance.
UPDATE
Following Pekka's request, here's an illustrative scenario:
- Consider subdomain.example.com/test.html.
- test.html calls
.<script src="/code/js/test.class.js" type="text/javascript" ></script> - In test.class.js, there's
.$.ajax({ url: "/code/php/test.php", dataType : "json", data: {cmd : 'someCommand'}, success: callback()});
..
- Hence, at #2, it retrieves
(Correct!).common.example.com/code/js/test.class.js - While at #3, the AJAX request points to
(Incorrect due tosubdomain.example.com/code/php/test.phpsubdomain).
