This walkthrough will guide you through how to create and test a set of rewrite rules for the URL Rewrite Module. Prerequisites This walkthrough requires the following prerequisites:
This article provides an overview of the URL Rewrite Module and explains the configuration concepts that are used by the module. While the primary purpose of the module is to rewrite request URLs to more friendly URLs, you can also use the module to define rules that perform redirects, send custom responses, or abort requests.
Rewrite Rules Overview A rewrite rule defines url rewrite action querystring logic of what to compare or match the request URL with, and what to do if the comparison is successful. Rewrite rules consists of the following parts: Pattern — The rule pattern is used to specify either the regular expression or a wildcard pattern that is used to match URL strings.
Conditions — The optional conditions collection is used to specify additional logical operations to perform if a URL string matches the rule pattern. Within the conditions, you can check for certain values of HTTP headers or server variables, or verify if the requested URL corresponds to a file or directory on a physical file system.
Action — The action is used to specify what to do if the URL string matches the rule pattern and all the rule conditions are met.
Rewrite Rules Scope Rewrite rules can be defined in two different collections: Global rules are used to define server-wide URL rewriting logic. These rules are defined within the ApplicationHost. Distributed rules are used to define URL rewriting logic specific to a particular configuration scope.
This type of rule can be added on any configuration level by using Web. Distributed rules operate on the URL path, relative to the location of the Web. The rules are evaluated in the same order in which they are specified.
First, the URL is matched against the pattern of a rule. If it does not match, the URL Rewrite Module immediately stops processing that rule, and goes on to the next rule. If a pattern matches and there are no conditions for the rule, the URL Rewrite Module performs the action specified for this rule and then goes on to the next rule, where it uses the substituted URL as an input for that rule.
If a pattern matches and there are conditions for the rule, the URL Rewrite Module evaluates the conditions.
If the evaluation is successful, the specified rule action is performed, and then the rewritten URL is used as input to the subsequent rule A rule may have the StopProcessing flag turned on. When the rule action is performed i. By default, this flag is turned off. Rules Inheritance If rules are defined on multiple configuration levels, the URL Rewrite Module evaluates the rules in the following order: Evaluate all the global rules.
Evaluate a rule set that includes distributed rules from parent configuration levels as well as rules from the current configuration level. The evaluation is performed in a parent-to-child order, which means that parent rules are evaluated first and the rules defined on a last child level are evaluated last.
These server variables can be accessed by using a condition within a rule. For example, if a request was made for this URL: Note that the input URL string passed to a distributed rule is always relative to the location of the Web. For example, if a request is made for http: Current, in this context, means the value of the URL path when the rule is applied.
If there were any rules that preceded the current rule, they may have matched the original requested URL and modified it. The URL string that is evaluated against the pattern does not include the query string.Is it possible to use URL Rewrite to provide more complex query string functionality than the "Append query string" checkbox that it has?

This means that the query string from the original URL is appended to the substituted URL. Redirect action A CustomResponse action causes the URL Rewrite Module to respond to the HTTP client by using a user .

This question has received quite some attention since it was posted and I wanted to write a simple guide for this module here.
