Could someone suggest any good site/s that I can learn about how to use .htacess??

Thanks in advance.

There are many to choose from, this one was top of the list after doing a quick search:

Lats...

That was a very useful tutorial, that for sure...

I was particularly impressed with the bit on hot linking, though for the life of me I can't get it to work. I tested between two domains I run off the same server and it didn't seem to work.

Here is the code that it instructed me to place in my .htaccess, which I did:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ - [F]


Of course I replaced my own domain name for "mydomain.com" - I am pretty sure I have mod_rewrite on my server. Is there any other way to check if it is there?
