Inject IP address into http header

Hi All,

 

 

Hoping someone out there can help, little new to iRules.

 

I was hoping that I could create a rule that would inject the source ip address into the http header.

 

The reason for this that the server behind the F5 needs to know what IP address each request is coming from, as we have enabled snat on the virtual Ip, the source ip is always changed to that of the F5.
