ISAPI_Rewrite 3 Lite is a Freeware URL rewriter for IIS, compatible with Apache mod_rewrite. It supports nearly all Apache mod_rewrite features. It is used for search engine optimization, to proxy another server's content, stop hotlinking or strengthen server security.


  • Offers same syntax and behavior as Apache mod_rewrite, but supports only global httpd.conf configuration
  • Regular expressions for flexible and powerful configurations.
  • Extremely fast and highly scalable pure C++ code.


  • Search engine optimization.
  • Prevent content leeching (direct linking).
  • Hide file extensions.
  • Block specific hosts, referrers or annoying robots.
  • Content negotiation - serving different files for different language or different browsers.


  • Windows 2000 with IIS 5
  • Windows XP with IIS 5.1
  • Windows 2003 with IIS 6
  • Windows Vista with IIS 7
  • Windows Server 2008 with IIS 7
