redirect to a different vs based on topology?

I have GTM's and LTM's in my environment. I received a requested today to redirect a site based off the user's IP address.

 

 

Here is the example:

 

 

www.mywebsite.com

 

and

 

www.mywebsite.co.uk

 

 

If a user from the UK hit's the .com site, they are redirected to the UK site, and vica versa. I don't think the topology feature will work in the GTM, since that is for the whole GTM, not on an individual wide ip basis.

    Hi Nick,

     

     

    At a DNS level, I think you could use the whereis command (Click here) in GTM to check the client/LDNS IP address and answer with the the .co.uk IP for UK clients and the .com IP address for non-UK clients.

     

     

    It might be more ideal to also do this check at the VIP level and send an HTTP redirect to UK clients who request the .com VIP and redirect non-UK clients who request the .co.uk VIP. I believe the whereis command will be available in LTM iRules in the upcoming 10.1.0 release.

    Yeah I was thinking that as well. At the LTM/VIP level, I don't think it has a topology database though, so I would have to put together a list of subnet's that are from the UK right?

    In 10.1, you can use the whereis command in LTM. But for now, you could load the GeoIP info for the UK to a datagroup and then reference it for the LTM iRule.

     

     

    There is a very useful post on this here:

    I've heard 10.1 should be released any day now, but until then I don't think the docs are available. I tested the whereis command in a 10.1 beta version after getting confirmation from F5 that it should work:

    Note: I wouldn't suggest using 10.1 in production until a subrelease or two have been released.
