Get current default pool name in an iRule?

HI

you can try this

code
when CLIENT_ACCEPTED {
 Save the name of the VIP's default pool
set default_pool [LB::server pool]
}

when HTTP_REQUEST {
    if { ([string tolower [HTTP::uri]] contains "/123/") } {
        pool POOL_A
    }
    elseif {([string tolower [HTTP::uri]] contains "/456/") } {
        pool POOL_B
    }
    else {
    pool $default_pool
    }
}

have a good day!
