Redirect to 404 if there is "?" (Question mark) in the url

Question

User1494574938 posted

Friends, 

I am trying to redirect a page if there is a "?" in the URL using web.config,  but it is not working

I added a condition to negate if the param is "?"

The rule is 

    <rule name="Activa-LT_rd" stopProcessing="true">
    <match url="Activa-LT.asp" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
    <add input="{UNENCODED_URL}" pattern="\?" negate="true" />
    </conditions>
    <action type="Redirect" url="Activa-LT/" redirectType="Permanent" />
    </rule>

Appreciate any help

If you study some basic concepts of URLs, you will see that "?" in the browser's address bar only indicates a query is appended, https://en.wikipedia.org/wiki/Uniform_Resource_Identifier

Then on IIS side you should check if the query exists, like https://stackoverflow.com/questions/12648281/iis-rewrite-rule-to-check-for-querystring-and-add-it-if-its-not-there
