Rules to redirect based on URL

... and in fact, I think I have a bit of a bug there with the non-glob matches, so here is a variant that uses a data group :).

create ltm pool pool-user1-context members add { 192.168.1.1:80 { } }
create ltm pool pool-user2-context members add { 192.168.2.1:80 { } }
create ltm pool pool-user3-context members add { 192.168.3.1:80 { } }

create ltm data-group internal dg-user-server type string records add { \
   User1 { data pool-user1-context } \
   User2 { data pool-user2-context } \
   User3 { data pool-user3-context } \
}

create ltm rule context-to-server {
when RULE_INIT {
    set static::uc_user_server_dg dg-user-server
}


when HTTP_REQUEST {
    set context [getfield [HTTP::uri] / 2]
    set swpool [class lookup $context $static::uc_user_server_dg]
    
    if { $swpool ne "" } {
        set nuri [substring [HTTP::uri] [string length "/$context"]]
        if { $nuri eq "" } {
            HTTP::uri /
        } else {
            HTTP::uri $nuri
        }
        
        pool $swpool
    }
}
}

It makes sense to define a default pool for the Virtual Server to which this rule would be applied.
