Nimbostratuslayer 3 and layer 7 traffic management
I am familiar with F5 LTM but not so much with GTM product. We have used LTM extensively in our stack to terminate SSL and then route traffic based on HTTP URL value etc. From what I was able to understand, while F5 GTM supports iRules, the GTM only works on DNS based events and it does not have similar capability that exists in the LTM product, i.e. route based on HTTP URL values etc.. ?
I have a scenario where there are 2 different sites, each with its own LTM. I was asked if we can support the ability to "route HTTPS traffic at the GTM layer through inspection of both DNS records as well as URL values."
e.g. https://acme.com/gateway/app-01/data/ --> this should go to site 1 (based on app-01) https://acme.com/gateway/app-02/data --> this should go to site 2 (based on app-02)
I am guessing that this isn't possible but it's worth asking for validation. I would appreciate also if there are any best practices out there for such a problem. The number of variations (app-01, app-02) is relatively small (i.e. less than 10-12 combinations)

Hello
You're right, the GTM receives DNS requests and sends responses based on L3 and geoip. To do what you want you could use different sub domains, ie secure.acme.com for https and acme.com for http. But since you seem to already know what you're talking about I guess you have already thought about this. :)
Kind regards, Patrik
