Block requests from specific domain to my web application

[iRule]

Dear Community,

I need to block all http & https requests initiating from a specific domain xyz.com to my web application abc.com . Please inform how we can acmmplish this from LTM iRule, LTM Policy or ASM Policy.

Hi iRule,

with iRules it could be done with the commands RESOLV::lookup or NAME::lookup. However both commands have been deprecated in BIG-IP 15.1.

Just a comment - if there is no PTR record for the xyz.com domain this way of blocking won't work.
