.htaccess files not the same....

I'm seeing two different .htaccess comments being suggested...

In the .htaccess file that is in the 1.7 zip folder it has:

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

In the install instructions Readme file it has:

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

These are different.... I don't know if they function the same or not. Does it matter which one I use?

It appears one is for Apache and mod_rewrite and the other is for IIS and ISAPI_Rewrite

I suppose if I'm using the IIS and ISAPI_Rewrite now then I should continue?

If you are already using vBSEO 3.0.0, the IASPI_Rewrite rules included should already include the line for Sitemap, so no changes should be needed.

Thanks
