Hello Ahmad,

I don't think this is a good idea,

 

Altough some configurations use "forwarding" type virtual servers with destination 0.0.0.0 for traffic routing, a Virtual Server with destination 0.0.0.0:80 will only match client-side traffic that otherwise would be dropped because no listener was configured for traffic destination.

 

If there are Virtual Server with a best match (destination address/port), client traffic will be processed by those VS's regardless of this configuration.

 

Moreover, to process this as HTTP traffic you will be required to apply a HTTP profile at least (this will allow you to operate in full L7), which if I'm not wrong is only available in a Standard-type Virtual Server -- or at least, not in a Forwarding-type; making me believe you'll need to configure forwarding manually anyways.

 

Every BIG-IP unit comes with a set of pre-defined iRules, and one of those has code for HTTP redirect. In my opinion, it will be much easier to just refer the iRule in every VS where you have this requirement.
