How to switch between the pools based on the listening port into the Irule

A simple example:

when CLIENT_ACCEPTED {
    switch [TCP::local_port] {
        "8080" { pool Poola }
        "1099" { pool Poolb }
    }
}

You could also dump these into a string-based data group. Example:

8080 := Poola
1099 := Poolb

And use a more dynamic version of the iRule:

when CLIENT_ACCEPTED {
    if { [class match [TCP::local_port] equals my_port_dg] } {
        pool [class match -value [TCP::local_port] equals my_port_dg]
    }
}

ok Kevin thanks, so will try both the ways and let you know.

And also Kevin:

By applying the below Irule, also wanted to edit/add this irule saying to redirect it to https when the traffic hit to http.

when CLIENT_ACCEPTED { switch [TCP::local_port] { "8080" { pool Poola } "1099" { pool Poolb } } }

Thanks and Regards Parveez

Switch to this then:

when HTTP_REQUEST {
    switch [TCP::local_port] {
        "8080" { pool Poola }
        "1099" { pool Poolb }
        "80" { HTTP::redirect "https://[HTTP::host][HTTP::uri]"
    }
}
