Question

I want to rewrite my URL Querystring in IIS i.e to update my ip=0

Actual URL
http://test.com/track/?ip=1&_=12345
Expected result
http://api.com/track/?ip=0&_=12345
MY Regex
http://test.com/([_0-9a-z-]+)/([?_0-9a-z]+)=([0-9]+)(.*)
http://api.com/{R:1}/{R:2}=0{R:4}
Can you please help me?

For the different web site, Redirect is a preferable way to Url Rewrite. Otherwise, Rewrite is applicable to the same web site.

We need to match the query string, and then we can assign the fragment of the query string to the new action.
ip=([0-9]+)&_=([0-9]+)
Please refer to the below screenshot.
WebConfig.
<rewrite>
<rules>
<rule name="MyRule" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{QUERY_STRING}" pattern="ip=([0-9]+)&_=([0-9]+)" />
</conditions>
<action type="Redirect" url="http://localhost/track?ip=0&_={C:2}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
