IIS - url rewrite: Problem with url rewrite rules not triggering

Question

Hi,

I have some users landing on my page with this url:

https://www.dummydomain.eu/eifeler-regel-letzebuergesch-checker?l=lu

That page does not exist anymore so they redirected to:

https://www.dummydomain.eu/lu/eifeler-regel-letzebuergesch-checker

I set up this rule which does not seem to trigger at all:

                <rule name="RedirectEFChecker" stopProcessing="true">
                    <match url="^(.*)(\/.*)\?l=(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{QUERY_STRING}" pattern="l=([a-z]{2})" />
                    </conditions>
                    <action type="Redirect" url="https://www.dummydomain.eu/{C:1}/{R:2}" appendQueryString="false" />
                </rule>

what did I miss?

The second issue is that I have another rule that should block all traffic aiming at any url that's not part of my domain.

                <rule name="BlockNichtMeins" stopProcessing="true">
                    <match url=".*" negate="true" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{URL}" pattern="\/(de|en|fr|lu)/(admin|agb|dsgvo|eifeler-regel-letzebuergesch(-checker)?|grammar|impressum|index|inhouse|interpunkt|jobs|letzebuergesch-(laenner|verben)|reference|transdata(2|ag)?|translations|verb)$" negate="true" />
                    </conditions>
                    <action type="AbortRequest" />
                </rule>

but it does not work, what did I miss here?

You can try this rule:

 <rule name="test" stopProcessing="true">  
     <match url="^eifeler-regel-letzebuergesch-checker$" />  
        <conditions>  
           <add input="{QUERY_STRING}" pattern="l=([a-z]+)" />  
        </conditions>  
     <action type="Redirect" url="https://www.dummydomain.eu/{C:1}/{R:0}" appendQueryString="false" />  
 </rule>  

The second issue is that I have another rule that should block all traffic aiming at any url that's not part of my domain.

Answer 2

Hi @Sam Wu-MSFT ,

with that rule I now get:

The expression "https://www.dummydomain.eu/{C:1}/{R:2}" cannot be expanded.

Regarding the second rule:

Let's say my domain only has the following pages:

/index
/eifeler-regel-letzebuergesch-checker
/agb
/dsgvo

I now want anyone trying to access a non-existent page to be blocked:

https://www.dummydomain.eu/admin
https://www.dummydomain.eu/cdn-cgi
https://www.dummydomain.eu/mysql
https://www.dummydomain.eu/feed
https://www.dummydomain.eu/someotherstring
https://www.dummydomain.eu/

so the existent ones should be whitelisted any other page blacklisted and thus blocked.

I hope that explanation helps.
