Simple Mod_Rewrite Help

[clanstyles]

Okay, I googled about "Chain" Mod_Rewrites, I came up with nothing. From what I understand, they are like index.php?a=nameofthething thats turned into /nameofthing/

 

Then with chain on it can go on to check for many other arguments that would arise like mabye the id /nameofthing/id/ or something else.

 

Then theres my problem of this:

#Rewrite Rules

RewriteRule ^([A-Za-z0-9-]+)/?$ index.php?module=$1 [QSA,C]

RewriteRule ^catagories/([A-Za-z0-9])$ index.php?module=catagories&cat=$1 [QSA,C]

 

As you can see I tried to use Chain, couldn't understand it. Then, I just tried that. it is supposed to turn out /catagories/blahw/ but it gives a 404 error.

What about this?

RewriteEngine on
RewriteRule ^([A-Za-z0-9-]+)/?$ index.php?module=$1
RewriteRule ^catagories/([A-Za-z0-9]+)$ index.php?module=catagories&cat=$1
