Redirecting request to different pools based on port number

I have two application servers as members to multiple pools. I currently created multiple VS with unique port service.

 

As you can see from example below, I would like users to be able to, lets say if in first url page (tuesday), click a link to "friday". It currently works as intended but I have to create VS for each port. I want to reduce the number of VS and conserve the IP addresses.

 

I am unable to test this because lack of testing environment. And as irule newbie, I dare not monkey with production network.

 

when HTTP_REQUEST {

 

switch -glob [HTTP::host] {

 

http://example.mtd.today.com:8088/tuesday/ { pool Stagin_Pool }

 

http://example.mtd.today.com:8089/wednesday/ { pool Management_Pool }

 

http://example.mtd.today.com:8090/thursday/ { pool Development_Pool }

 

http://example.mtd.today.com:8091/friday/ { pool Test_Lab_Pool }

 

default { pool Production_Pool }

 

}

 

}

 

Thanks for your help.

    You don't have to create multiple VIPs at all. With the iRule you have here, minus the port numbers, you can host all of the applications on a single IP and port. I should also point out that [HTTP::host] is only returning the host name and not the URI, so because the host name is the same for all of these, you can create a single VIP and modify your iRule to look something like this: 

    
when HTTP_REQUEST {
     switch -glob [string tolower [HTTP::uri]] {
          "/tuesday*" { pool Stagin_Pool }
          "/wednesday*" { pool Management_Pool }
          "/thursday*" { pool Development_Pool }
          "/friday*" { pool Test_Lab_Pool }
          default { pool Production_Pool }
     }
}
