irule with different pool by URI

Can anyone help me?

My problem is that this Irule doesn't work correctly due an error?

when HTTP_REQUEST {

log local0. " l'HOST e' [HTTP::host], l'URI e' [HTTP::uri]"

switch -glob [HTTP::uri] {

"/xmlpserver/*" -

"/analytics/*" -

"/em/*" -

"/analytics-ws/*" -

"/wsm-pm/*" -

"/bimiddleware/*" -

"/mapviewer/*" -

"/ui/*" -

"/rtis/*" -

"/schema/*" -

"/ws/*" -

"/bioffice/*" -

"/biofficeclient/*" -

"/console/*" {

log local0. "CSE - l'URI e' [HTTP::uri], sono dentro al pool-www-obi-v"

pool pool-www-obi-v-7777

persist source_addr 3600

}

default {

log local0. "CSE - l'URI e' [HTTP::uri], sono dentro pool-www2.farm-v"

pool pool-www2.farm-v

persist source_addr 3600

}

}

}

When I try to connect to the virtual server like http://www.acme.com/xmlpserver/ the irule log show me the correct pool (obi pool) but with the tcpdump I see the packet dispaced on the default pool.

If I put any caracter after the slash like: http://www.acme.com/xmlpserver/xyz the correct pool is engaged.

I've tried to remove the asterisk, the last slash...but I'm not able to resolve this problem
