I have already created a topic about query strings, unfortunately the question was closed and no one answers anymore.
For example, I want to redirect from splash.aspx?page=3 to a simpler url e.g. to splash3.aspx. I unfortunately have no backend code where the query string can respond, so I need an alternative. How can I configure url rewrite?
In your web.config, add the following nodes:
<rewrite>
<rule name="Redirect splash page 3" stopProcessing="true">
<match url="splash\.aspx$" />
<conditions>
<add input="{QUERY_STRING}" pattern="page=3" />
</conditions>
<action type="Redirect" url="splash3.aspx" redirectType="Temporary" />
</rule>
</rewrite>
