.htaccess rewrite rule to mongrel rewrite rule

Server Mongrel
1

Hi All,

The application is running on mongrel cluster and its used to serve
different contents for each domain and I had implemented the cache per
domain level using the below plugin:

Now the problem is, since the mongrel bypasses the .htaccess
configuration and I am new to mongrel rewrite rule. So it would be of
great help, if you can let me know the right rewrite rule for mongrel
for the below .htaccess

RewriteMap uri_escape int:escape
<Directory /path/to/my/rails_app/public/>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} GET [NC]
RewriteCond
%{DOCUMENT_ROOT}/cache/%{HTTP_HOST}%{REQUEST_URI}%{QUERY_STRING}.html -f
RewriteRule ^([^.]+)$
cache/%{HTTP_HOST}/$1${uri_escape:%{QUERY_STRING}}.html [L]

  RewriteCond %{REQUEST_METHOD} GET [NC]
  RewriteCond %{DOCUMENT_ROOT}/cache/%{HTTP_HOST}/index.html -f
  RewriteRule ^$ cache/%{HTTP_HOST}/index.html
</Directory>

Please do let me know.

Thank you for your helps!
