IIS 7.5 URL rewrite redirect rule for old URL to new URL

I am trying to map this old webform URL

http://www.mysite.com/Listing.aspx?mlsnum=T5017910

to this new MVC URL:

http://www.mysite.com/listing?id=T5017910

Somehow I cannot get it to work. My rule is as follows:

<rule name="My Listing Redirect Rule" stopProcessing="true">
    <match url="^Listing.aspx?mlsnum=([0-9a-z]+)" ignoreCase="true" />
    <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Redirect" url="listing?id={R:1}" redirectType="Permanent" />
</rule>

Any help is appreciated开发者_StackOverflow中文版.

Your <match url=...> need to escape the ? character try this instead:

<match url="Listing.aspx\?mlsnum=([0-9a-z]+)" ignoreCase="true"/>
