    Hello, something like this?

    when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::uri]] {
        "/uristarts*" -
        "*/uricontains/*" -
        "*/uriends" {
            persist none
        }
    }
}

    Regards.

    Sourav, If I understood your logic, the switch block should be:

    when HTTP_REQUEST { 
    switch -glob [string tolower [HTTP::uri]] {
        "/admin/*" -
        "/ads/*" -
        "/eavcs/*" -
        "/eaon/*" {
            persist none
            pool name
        }
        "/" {
            HTTP::redirect "https://website.com/admin";
        }
        default {
            if { [HTTP::cookie exists BIGipServer~pool pool_com] } {
                scan [HTTP::cookie BIGipServer~pool pool_com] {%[^.].%d.%d} myIpE myPortE unused
                set myIpH [format %08x $myIpE]
                set myIpD1 [expr 0x[substr $myIpH 6 2]]
                set myIpD2 [expr 0x[substr $myIpH 4 2]]
                set myIpD3 [expr 0x[substr $myIpH 2 2]]
                set myIpD4 [expr 0x[substr $myIpH 0 2]]
                set myIpD "$myIpD1.$myIpD2.$myIpD3.$myIpD4"
                set myPortH [format %04x $myPortE]
                set myPortD [string trimleft [expr 0x[substr $myPortH 2 2][substr $myPortH 0 2]] 0]
                node $myIpD $myPortD
            }
        }
    }
}
