The .htaccess file looks like this below. I've never really seen an .htaccess that looks like this.
Not sure what language or what code base it's using. What I would like to do is caching that looks like this:
http://gtmetrix.com/leverage-browser-caching.html
# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.72
RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 20
RewriteBase
# Block external access to the httpd.ini and httpd.parse.errors files
RewriteRule ^/httpd(?:\.ini|\.parse\.errors)$ / [NC,F,O]
# Block external access to the Helper ISAPI Extension
RewriteRule ^.*\.isrwhlp$ / [NC,F,O]
# Fix missing slash char on folders
RewriteRule ^([^.?]+[^.?/])$ $1/ [R,L]
RewriteRule /default.aspx / [r=301]
