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

    ok so the following irule works in a sense it matches fqdn and redirects to instructed node and port.. thats working perfect.

    when HTTP_REQUEST {
 
  switch -glob [HTTP::host] {
    fqdn1 { 
	HTTP::header replace Host "????" # < --- I want to replace the IP of node with the fqdn to verify certificate
	HTTP::redirect http://node:port1[HTTP::uri]
	if { [HTTP::uri] starts_with "/uri-X" } { HTTP::redirect http://node:port2[HTTP::uri] }
	}
    fqdn2 { 
	HTTP::header replace Host "????"
	HTTP::redirect http://node:port3[HTTP::uri]
	if { [HTTP::uri] starts_with "/uri-X" } { HTTP::redirect http://node:port4[HTTP::uri] }
	}
    fqdn3 { 
	HTTP::header replace Host "???"
	HTTP::redirect http://node:port5[HTTP::uri]
	if { [HTTP::uri] starts_with "/uri-X" } { HTTP::redirect http://node:port6[HTTP::uri] }
	}
  }
}

    But... the rewrite of host is not working. I tried putting in node IP, the fqdn etc but no dice... if this somehow works i will be happy 🙂

    what am I missing??
