Something like this in IIS should do it:

<code><configuration> <system.webserver> <rewrite> <rewritemaps> <rewritemap name="PortalMap"> <add key="domain1.com" value="1"> <add key="domain2.com" value="2"> </add></add></rewritemap> </rewritemaps> <rules> <rule name="Redirect LLMs.txt based on hostname" stopprocessing="true"> <match url="^LLMs\.txt$"> <conditions> <add input="{PortalMap:{HTTP_HOST}}" pattern="(.+)"> </add></conditions> <action redirecttype="Permanent" type="Redirect" url="https://{HTTP_HOST}/portals/{C:1}/LLMs.txt"> </action></match></rule> </rules> </rewrite> </system.webserver> </configuration></code>

This is very usefull if you have many portals. Just use the PortalMap and add the hostnames for the diffent portals and redirect accordingly

 

 

Would it be better for the action to be a Rewrite so we do not rely on the AI crawler following 301/302 redirects?

I would've suggested something similar to what Mariette did... It also parallels the way multiportal Robots.txt files work.

Would you be so kind to copy paste the code? (Daretoask :-) 

the value of domain1.com would be the portal ID?
for instance dnncommunity.org value=1, dnnsoftware.com value=2

?

Tycho,
Mariette said she tried a few times to post it and I just tried it and I feel her pain :)
(the good news is we have an issue to work on posting of XML into the forums, which hopefully we can improve :) )

BTW you didn’t post this using quick reply, correct?

Sometimes when the replies disappear into the ether, I honestly think it’s a cloudflare issue vs forums or dnn. Were you posting anything unusual like xml or HTML?

When I've seen my replies disappear, it's been because CloudFlare needed to do another check before it allows a post.  Then, I go back in browser history.  The posted message is usually there (but I usually copy it beforehand anyway).  From there, I can post again.  I'm not sure which setting was enabled for this behavior and how to adjust it.  🤔 

I think the issue with disappearing posts is now fixed because we I changed configuration in CF but John and me are looking into this also. Pls, check the thread in the webmasters forum.
