IIS URL Rewrite enables Web administrators to create powerful rules to implement URLs that are easier for users to remember and easier for search engines to find.
For more information you can read the below url: http://www.iis.net/downloads/microsoft/url-rewrite
See the below example redirect from one Domain to another:
IIS URL Rewrite will add the rewrite rules into web.config
<?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Domain switch" stopProcessing="true"> <match url=".*" /> <conditions> <add input="{HTTP_HOST}" pattern="(www.)?site1.com" /> </conditions> <action type="Redirect" url="http://www.site2.nl/{R:0}" /> </rule> </rules> </rewrite> </system.webServer> </configuration>
