IIS Mod Rewrite Pro descriptionAn utility that implements nearly all Apache mod_rewrite featuresIIS Mod-Rewrite is a URL rewriting module for Internet Information Services (IIS). The logic of URL manipulation runs on regular expression (regex) based rules.

The configuration syntax and the behavior of IIS Mod-Rewrite engine are compatible with Apache's mod_rewrite, so that configurations from Apache can be easily migrated to IIS and vice versa.

How it works

The URL manipulation mechanism of IIS Mod-Rewrite is rule based. When a requested URL matches a rule, the corresponding text substitution is performed on that URL.

Taking a deeper look, every rule is based on a regular expression, on which the input URL is tested. If a match occurs, then IIS Mod-Rewrite proceeds with the substitution of the URL. The substitution text consists of a combination of static and dynamic text strings. The inserted dynamic strings can be substrings of the matched URL
