    Heya,

    You could use a policy for this but here is a quick iRule for you too (keep in mind you could also use a datagroup within the iRule).

    when HTTP_REQUEST {

switch -glob [string tolower [HTTP::uri]] {
    "/def/ghi/account*" {
        pool  servers_8100
    }
    "/def/ghi/customer*" {
        pool servers_8200
    }
    "/def/ghi/equipment*" {
        pool servers_8300
    }
    "/def/ghi/order*" {
        pool servers_8400
    }
    "/def/ghi/statement*" {
        pool servers_8500
    }
    "/def/ghi/payment*" {
        pool servers_8600
    }
    "/def/ghi/financials*" {
        pool servers_8700
    }
    default {
        pool servers_default_pool
    }
}
}

    You could run the iRule/policy on both virtual servers (443/7443), just make sure any client/server ssl profiles are applied appropriately.

  • Below is an example use similar else if statements for the other pools and URI
  • Assign the iRule and not the pool 
        when HTTP_REQUEST {
if { ([HTTP::uri] starts_with "/def/ghi/account") } {
pool 8100
}elseif { [HTTP::uri] starts_with "/def/ghi/customer" } {
pool 8200
}elseif { [HTTP::uri] starts_with "/def/ghi/equipment" } {
pool 8300
}
}
