ISAPI Rewrite is a powerful URL manipulation engine based on regular expressions. It acts mostly like Apache's mod_Rewrite, but it is designed specifically for Microsoft Internet Information Server (IIS).

ISAPI Rewrite is an ISAPI filter written in pure C/C++ so it is extremely fast. ISAPI Rewrite gives you the freedom to go beyond standard URL schemes and develop your own scheme.

ISAPI Rewrite 2.0 Product Review

  1. No IIS service restart required.
  2. Easy product installation and comes with default "global configuration" for the entire server (all sites will be affected by these global rules).
  3. Better support for multiple virtual sites. Just need to drop in "local configuration" file and it's up and running right away. Again, no IIS restart here either.
  4. Excellent product documentation and examples.
  5. Configuration file can be edited live at anytime.
  6. ISAPI has a small stand alone Regular Expression Test Utility GUI app for developers to test/debug expressions before use.
  7. Error log file produced if there is any error in the production configuration file.
  8. ISAPI shows full documentation of all available expressions.
  9. ISAPI has Optimization Flag to clean up URL Encode before parsing and a Ignore Case-sensitive Flag.

There are many more features we haven't used or may never use. ISAPI has many "http headers" manipulation examples in its documentation.
