Now Available: URL Rewriter Tech Preview 1

Today we are releasing Technical Preview 1 of the URL Rewrite Module for IIS 7.0.

The URL Rewrite Module provides a rule-based rewriting mechanism for changing request URL’s before they get processed by IIS. The module supports regular expression based URL rewriting logic or a simpler wildcard-based URL rewriting logic. Rewriting decisions can be based on the URL, HTTP headers and server variables. While the primary purpose of the module is to rewrite URLs, it also has functionality to perform redirects, send custom responses and abort requests based on the logic expressed in the rewrite rules.

Feature Set

Here is a quick feature overview:

  • Rules-based URL rewriting engine. Rules are used to compare/match the request URL with and what to do if comparison was successful.
    • Regular expression pattern matching. Rewrite rules can use ECMA-262 compatible regular expression syntax for pattern matching.
    • Wildcard pattern matching. Rewrite rules can use Wildcard syntax for pattern matching
  • Back-references to patterns and conditions. Back-references are used to capture parts of a matched URL so that it can be re-used later in a rule when constructing a substitution URL string. Back-references are available with regular expression and wildcards patterns.
  • Global and distributed rewrite rules. Global rules are used to define server-wide URL rewriting logic. Global rules cannot be overridden or disabled by lower configuration levels. Distributed rules are used to define URL rewriting logic specific to a particular configuration scope, e.g. an web application.
  • Access to server variables and http headers. Server variables and HTTP headers provide additional information about current HTTP request. This information can be used to make rewriting decisions or to compose the output URL.
  • Various rule actions. Instead of rewriting a URL, a rule may perform other actions, such as issue an HTTP redirect, abort the request, or send a custom status code to HTTP client.
  • Rewrite maps. Rewrite map is an arbitrary collection of name-value pairs that can be used within rewrite rules to generate the substitution URL during rewriting. Rewrite maps are particularly useful when you have a large set of rewrite rules, all of which use static strings (i.e. there is no pattern matching used). In those cases, instead of defining a large set of simple rewrite rules, you can put all the mappings between input URL and substitution URL as keys and values into the rewrite map, and then have one rewrite rule which references this rewrite map to look up substitution URL based on the input URL.
  • UI for managing rewrite rules. Rewrite rules can be added, removed and edited by using "URL Rewrite Module" feature in IIS Manager.
  • GUI tool for importing of mod_rewrite rules. URL rewrite module includes a GUI tool for converting rewrite rules from mod_rewrite format into IIS format.

  • Oh Yeah!!! Nice Addition!

  • Im agree.

  • This is a great script. However near the end of the script the drive letter F is hardcoded.
    REM Make sure Service Pack and Hotfix Installers know where the IIS root directories are
    reg add HKLM\Software\Microsoft\inetstp /v PathWWWRoot /t REG_SZ /d f:\inetpub\wwwroot /f
    reg add HKLM\Software\Microsoft\inetstp /v PathFTPRoot /t REG_SZ /d f:\inetpub\ftproot /f


    Also noticed if the new FTP 7.0 is installed (after running this script) it goes back to default MS install location.
    Thanks for a great article and script.
