Issues with Mod_Rewrite

[jhecht 0]

Hey everybody, been a long time. I come bearing a question. I'm working on a website for a couple of buddies, and I'm trying to add some ambiguity in the AJAX calls by using Mod_Rewrite.

RewriteEngine on

RewriteRule ^([A-Z][A-Za-z]+)\\?(.*)?$ /modules.php?mod=$1&$2

At first I thought there was an error in my Regular Expression, so I decided to test it out in Javascript. Say I am trying to request

/Data?user_id=1

The Javascript version returns exactly what it should, [Data,user_id=1], but the page redirects to /modules.php?mod=Data. There isn't even the ampersand, anyone have any ideas about why this isn't working? By the way, it works just fine for

/Data

Redirecting to

/modules.php?mod=Data
