F5 AppWorld 2024 session proposal deadline extended to Friday, December 8th!
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.
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.
