R – IIS7 Url Rewrite – Redirect from {any}.aspx to {any}

asp.net-mvciis-7redirecturl-rewriting

I am converting my website from Asp.Net Webforms to Asp.Net MVC. I want to redirect all my old .aspx files to drop the .aspx. I run IIS7 with the Url Rewrite module installed.

Example:

/about.aspx -> /about

The user will go to http://www.site.com/about.aspx and I want them redirected to http://www.site.com/about.

How do I do this using Url Rewrite? I don't want to have to do to each .aspx and put a meta-redirect in.

In your web.config file in system.webServer configuration section add:

<rewrite>
  <rules>
    <rule name="WebFromsToMVC" stopProcessing="true">
      <match url="^(.*?)\.aspx\?*?.*$" />
        <conditions>
          <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
          <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
        </conditions>
      <action type="Rewrite" url="{R:1}" />
    </rule>
  </rules>
</rewrite>

R – What’s the simplest way to rewrite Urls in ASP.NET MVC / IIS7

Starting with IIS7, IIS ships with a module that can be used for rewriting URLs.

http://learn.iis.net/page.aspx/460/using-url-rewrite-module/

"The Microsoft URL Rewrite Module for IIS 7.0 provides flexible rules-based rewrite engine that can be used to perform broad spectrum of URL manipulation tasks, including, but not limited to:

Enabling user friendly and search engine friendly URL with dynamic web applications;

Rewriting URL’s based on HTTP headers and server variables;

Web site content handling;

Controlling access to web site content based on URL segments or request metadata."

Well, it turns out that for security reasons you need to explicitly allow whatever server variables you wish to modify in the applicationHost.config (see http://learn.iis.net/page.aspx/665/url-rewrite-module-20-configuration-reference#Allowed_Server_Variables_List).

Therefore, the following does the trick in the Web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
    <rewrite>
        <rules>
            <rule name="IE56 Do not gzip js and css" stopProcessing="false">
                <match url="\.(css|js)" />
                <conditions>
                    <add input="{HTTP_USER_AGENT}" pattern="MSIE\ [56]" />
                </conditions>
                <action type="None" />
                <serverVariables>
                    <set name="HTTP_ACCEPT_ENCODING" value="0" />
                </serverVariables>
            </rule>
        </rules>
    </rewrite>
</system.webServer>

As long as the applicationHost.config has:

<location path="www.site.com">
    <system.webServer>
        <rewrite>
            <allowedServerVariables>
                <add name="HTTP_ACCEPT_ENCODING" />
            </allowedServerVariables>
        </rewrite>
    </system.webServer>
</location>
