HI Vitor,

corrected some portions...

when HTTP_REQUEST { 
        if { [active_members pool_YYYY] > 0 } then { 
            pool pool_XXXX 
        } else { 
            HTTP::uri "/test[HTTP::uri]" 
            pool pool_ZZZZZZZ 
        } 
}

Note1: The 

-list
option of 
[active_members -list pool_YYYY]
command is not required to count the numbers of active pool members. The -list option would deliver a string containing the IPs and Ports of every available pool members, which produces unnecessary overhead.

Note2: If you want to ad a trailing string to the 

[HTTP::uri]
you could easily substitute the new string, based on the new trailing string and the old value (aka. 
"/test[HTTP::uri]"
).

Cheers, Kai
