validate http payload on a third party server before releasing

Hi,

 

 

I'm new to F5. I would like to know if, using iRules, I can have HTTP:payload validated against a third-party component (say, an antivirus server) before letting the http request hits its destination node.

 

 

Can iRules do that ? Or do you see a better way to achieve such task ? Does F5 LTM support iCap ?
