Dear All,  
I would like to add port to the incoming Host request header if that not included it.  
I think I have managed to solve the problem in the way mentioned below. I just would like to ask for the experienced veterans is there any problem with this solution or is there any easier one?

acl port\_exists req.fhdr(Host) -m sub “:”  
http-request set-var(req.h\_host) req.fhdr(Host),lower  
http-request set-header Host %[var(req.h\_host)]:%[dst\_port] if !port\_exists

Thank you very much!
