.htaccess mod_rewrite Question
 

Is it possible to use mod_rewrite to change the url from something like this...

domain.com/blah.php?id=45

To the following:

domain.com/blah/keyword/

If the data that I want to have in the new URL is only included in the page using calls to an SQL database and each page is dynamic?

Yeah it's possible.
Here's some good info to learn:

Short answer is yes.

domain.com/blah/keyword/ is just a nicer looking alias for something like domain.com/?dir=blah&id=keyword

Search pretty urls.

Thanks guys :)
