ISAPI_Rewrite – Help

Hello,

I am trying to make my blog search engine friendly and have been told that I can do this using ISAPI_Rewrite on my Windows based hosting.

Originally (before I knew that I couldn’t use mod_rewrite), I was told to upload a .htaccess file that contains:
# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

I posted this on the Helicon forum hoping that they could give me the ISAPI_Rewrite equivelant and was told:
Unfortunately this part cannot be translated directly-

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

Current version of ISAPI_Rewrite cannot check for file existance. You can try to translate these rules by finding some common for all URLs that need to be rewritten and writing a rule based on this mark.

Can someone please tell me how I can make this work? Please keep in mind that I am a novice.

Thank you for your time,

Robert
