Anuj Sethi 09:34 31 Oct 14

Thanks man.. I got it. Great work done. Its a one stop shop for all rewrite formulas :)

rio 11:37 25 Nov 14

I am trying to do a mod rewrite where it checks if the referring uri or clicked link contains a variable xyz and redirect it to another page. Or if referring uri/url has a variable ABC set, rest it to blank. Any ideas?

Billy 15:58 23 Mar 15

Good list - we also started using http:/htaccesscheatsheet.com/ (your list here has more directive/flags/server variables etc, but that website has some things you can just copy/paste in.

Billy 15:13 4 May 15

The link in my previous comment was a typo - it should be http://htaccesscheatsheet.com/ :)

what does exclamation mark (!) mean?

Namita 09:22 15 Feb 16

I have a Godaddy domain and I'm trying to enable cleaner urls so that a user can write www.abc.com/xyz instead of having to write www.abc.com/xyz.php but cannot get it to work. What am I doing wrong?

RewriteEngine On
Options +FollowSymLinks -MultiViews -Indexes
RewriteRule ^xyz$ xyz.php [NC,L]
