Mod_rewrite for IIS

Freshness Warning
This article is over 17 years old. It's possible that the information you read below isn't current.

One of the most useful features of Apache is mod_rewrite, a module that allows Apache to translate requests for one URL into another. For instance, if your ecommerce site uses a URL like, you can use mod_rewrite so that shoppers can instead type and bookmark Mod_rewrite will transparently translate that URL into what the server needs.

There are now two modules for IIS that perform the same type of function. IISRewrite implements most of mod_rewrite’s configuration and is used in much the same way as the Apache module. It costs $200.

ISAPI_Rewrite is very similar. It also includes most of the features of mod_rewrite and uses a text configuration file like Apache. It comes in three versions. A free version is available, but will be difficult to use if you host more than one site on a single Web server. A full version that supports different configuration files for each virtual site costs $46 per machine or you can buy an enterprise-wide license for $418.

Try this: ISAPI filter that rewrites URLs, something like Apache's mod_rewrite. It uses regular expressions (via PCRE). Implemented in C, Open source, BSD-style license. Compiles with the (free) Microsoft Visual C++ 2003 toolkit. The code does not use MFC. The ISAPI filter includes a test tool that allows you to test your rewrite rules against a set of sample URLs that you provide.

Free and open source?

IIS Mod-Rewrite ( ) is a solid solution with true mod_rewrite compatibility and .htaccess support. Rich settings, regex tester, automatic updates, and version history! IMO it's by far the best.

It looks that IIS Mod-Rewrite has a lead over the other solutions. I recently visited ISAPI Rewrite and it looks they are running behind IIS Mod-Rewrite. They are rushing to copy IIS Mod-Rewrite and announced a new mod_rewrite compatible beta version. As far as I tried the beta version, it has a lot of design faults. Although it's syntax is similar with mod_rewrite, it's behavior is unfortunatelly a big mess. Hope they will improve it... Regarding that site does not even exist anymore. Regarding IISRewrite... this tool has not been updated since 2002! And it costs a whole fortune compare to what it offers. IMO, IIS Mod-Rewrite is by far the best solution.

I'd like to see the IP addresses of 'stan' and 'stock' as I reckon they are both the same people. Moderators; If they are then delete both of them as they are skewing opinion.

Clearly IIS Mod-Rewrite is THE enterprise solution in today's expanding global market. Demands for outstanding performance and flexible scalability require the greatest server solution!!

Thanks! I thought there's no mod_rewrite like function in IIS.
