How to write an iRule to redirect to multiple uri's and to specific TCP Port (81)

OK, how about this then:

when HTTP_REQUEST {
   set myURI [string tolower [HTTP::uri]]
   if { $myURI contains "site-a" } {
      HTTP::uri /site-A[HTTP::uri]
      pool site-A
   } elseif { $myURI contains "site-b" } {
      HTTP::uri /logon/logon.html
      pool site-B
   } else { pool Default_Pool }
}

The pool for site A would contain the appropriate list of port 80 servers, and requests for any URI /already/ containing the string "site-A" would now include that string twice:

* URI sent by client: /site-A/somedir/somefile.txt

* URI sent to server: /site-A/site-A/somedir/somefile.txt

The pool for site B would contain the appropriate list of port 81 servers, and any requests for any URI containing "site-B" would be changed to request the login page:

* URI sent by client: /site-B/somedir/somefile.txt

* URI sent to server: /logon/logon.html

Defaul_Pool must also be defined to include the appropriate list of port 80 servers, and requests will be forwarded unmodified.
