Rewrite https request to http node IP and Port

Hi I am trying to implement a apache rewrite config into a F5 VS/iRule

I need to rewrite a https request to node IP and Port. I would also like to have a switch to rewrite to same node ip but different port based on the FQDN.

Something like

when

http request on dns1.domain.com rewrite to http://node:port1

http request on dns1.domain.com/URI-X rewrite to http://node:port2

http request on dns2.domain.com rewrite to http://node:port3

http request on dns2.domain.com/URI-X rewrite to http://node:port4

http request on dns3.domain.com rewrite to http://node:port5

http request on dns3.domain.com/URI-X rewrite to http://node:port6

While I am figuring it out will be glad to get some idea's/irules :)

Cheers,

Rony
