GTM iRule to enhance Topology Records

Are there iRule commands that would allow locally significant (within the iRule only) decisions based in part on the same criteria that can be used in Topology Records (Request Source, Destination and Weight), but also on additional criteria? We want to manipulate the Destination "Data Center" based on 2 criteria, Reqeust Source being 1 criterion and some boolean variable being another.

    Ahh... Should be. However the iRule would probably have to be a GTM iRUle, and not an LTM iRule (They're the same language, but LTM iRules don't have access to the GTM information - e.g. The GTM Pool). GTM rules however are a bit more constrained and don't have access to some of the newer features of iRules.

     

    LTM iRules however have full access to the DNS request & response info, so you can directly alter the data being returned from there.
