htaccess syntax question

[insidedesign]

Hello, I am trying to do a url rewrite for the URL:
http://www.lakeeffekt.com/launch/ind...board&Itemid=6

to:
http://www.lakeeffekt.com/launch/forum/

I have so far:

RewriteEngine on RewriteRule ^index\.php?option=com_simpleboard&Itemid=6$ /forum/index.php [R=301,L]

It does not seem to be working. Does anyone have suggestions? note: I cannot setup a regular redirect due to the nature of the site.

RewriteEngine on

# if you are going to place this in your website's root directory
RewriteRule launch/index\.php?option=com_simpleboard&Itemid=6 launch/forum/ [R=301,L]

# if you are going to place this in "launch" directory
RewriteRule index\.php?option=com_simpleboard&Itemid=6 forum/ [R=301,L]

Hmm, I tried both suggestions and neither worked. Is this the error of the server? Or maybe the syntax?

My suggestion should work with typical apache + mod_rewrite setup.
First, check if your server supports url rewriting. If everything is OK - check your error log.
