mod_rewrite (again?!)

I was wondering is there a way I can use mod_rewrite module to translate URL's containing query strings into URL addresses that search engine spiders can follow, something like this:

instead of
http://www.mysite.com/products.php?id=22343

you get a string like this:
http://www.mysite.com/products.php/22343

I am hosting my site on a webhost that has a mod_rewrite module on, but doesn't allow me to change any configuration in httpd.conf file... so is there any way I can use .htaccess files to turn on whatever feature needs to be on?

Do a search in Apache forum under my username. I discussed this some time last year, it was the longest thread in Apache forum.

I found it at http://forums.devshed.com/showthrea...9203&forumid=15, and it helped me get most of the stuff working the way I wanted, except few more details:

I have found that these lines work just fine for me:

####################
DirectoryIndex index.php3
RewriteEngine on
RewriteRule ^([A-Za-z0-9_]+)$ index.php3?letter=$1
RewriteRule ^download/([0-9]+)$ download.php3?number=$1
####################

But the problem is how do I use this rewrite condition with FORM querying the database (more specifically using the download.php3 as my FORM ACTION), so that the url doesn't show the actual download.php3, but just /download/3824 or whatever the number of the database entry is.

Here, take a look, and let me know if you can help me out:
