need http redirect and then pool selection based on local port

You will probably want to add a default case to the iRule else you risk dropping requests for URIs which don't contain configurator or are exactly /. You can also use a switch statement to check the URI.

I don't understand the exact scenario, but you should be able to figure out more about what's happening by adding logging and using a browser plugin that lets you check the requests the client sends and the responses it receives.

when HTTP_REQUEST {

log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] to [HTTP::host][HTTP::uri]"
switch -glob [HTTP::uri] {
"*configurator*" {
pool poolB
log local0. "[IP::client_addr]:[TCP::client_port]: Matched configurator, selecting poolB"
}
"/" {
HTTP::uri "/QITF/faces/portal"
pool poolA
log local0. "[IP::client_addr]:[TCP::client_port]: Matched /, selecting poolA"
}
default {
pool poolX
log local0. "[IP::client_addr]:[TCP::client_port]: Matched default, selecting poolX"
}
}
}
when HTTP_RESPONSE {
log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::status] from [LB::server] (redirect? [HTTP::header Location])"
}

What is Fiddler? Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet
