rewrite syntax for isapi_rewrite

I had my rewrite rules fixed the other day here in the forums for vbSEO, and I just installed the sitemaps and the rewrite for my forum isn't working. I did notice the person who fixed the rules for me the other day did add in the rules for the sitemaps too, here is a copy:

Code:

RewriteEngine On
RewriteRule ^/forum/((urllist|sitemap).*\.(xml|txt)(\.gz)?)$ /forum/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

However if I go to the link, I got a blank page. If I remove the rule and go to the page directly, the page shows up and I can login. So what changes do I have to make to make the rewrite work?
Thanks

You DON'T have to modify rewrite rule for sitemap since you have vBSEO installed already (vBSEO has corresponding rewrite rule as well).

I changed it back to what it before I changed it and it still wont load
http://www.easymarketingforum.com/forum/vbseo_sitemap/
However, if I visit http://www.easymarketingforum.com/forum/vbseo_sitemap I get redirected to the forum listing page

Code:

[ISAPI_Rewrite]
# When hosting multiple sites on the same server, it is
# recommended to  limit the rewrite rules to the domain(s)
# where vBSEO is installed. Enable (remove '#' at the beginning
# to activate) the following rule and replace 'easymarketingforum.com'
# with your actual installation domain name.
RewriteCond %{HTTP_HOST} .*easymarketingforum.com
RewriteCond %{REQUEST_URI} !^/forum/(avatars|attachments|iconimages).*
RewriteRule ^(.*\.(?:gif|swf.*|jpg|png|css|xml|js|htm|txt|zip))$ $1 [I,L]
RewriteCond %{HTTP_HOST} .*easymarketingforum.com
RewriteRule ^/forum/((urllist|sitemap).*\.(xml|txt)(\.gz)?)$ /forum/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]
RewriteCond %{HTTP_HOST} .*easymarketingforum.com
RewriteCond %{REQUEST_URI} !/forum/(admincp/|modcp/|clientscript/|cpstyles/|images/|search\.php).*
RewriteRule ^/forum/(.+?)$ /forum/vbseo.php?vbseourl=$1 [L,QSA]

Here is your vbseo_sitemap interface: http://www.easymarketingforum.com/fo...emap/index.php
and sitemap: http://www.easymarketingforum.com/fo...p_index.xml.gz

So it is necessary to type in the file name after the / I was thinking it would automatically pick up index.php and display it when goin to http://www.easymarketingforum.com/forum/vbseo_sitemap/
Thank you.

You can also try to change last rewrite condition to:

Code:

RewriteCond %{REQUEST_URI} !/forum/(vbseo_sitemap/|admincp/|modcp/|clientscript/|cpstyles/|images/|search.php).*
