Need help with an iRule for HTTP Methods

You should copy these iRules as is.
First iRule

when HTTP_REQUEST priority 500 {

    set URI [string tolower [HTTP::uri]]

    if { ( [HTTP::method] == "PUT" ) } {
        switch -- -glob ${URI} {
            "/rws/api/v1/devices/*" -
            "/rws/api/v1/accounts/*"
            {
                pool POOL_POD1_RWSDEVICE
            }
        }
    } elseif { ( [HTTP::method] == "POST" ) } {
        switch -- -glob ${URI} {
            "/rws/api/v1/accounts/*"
            {
                pool POOL_POD1_RWSDEVICE
            }
            default
            {
                pool POOL_POD1_RWS
            }
        }
    }

}

Second iRule

when HTTP_REQUEST priority 500 {

    if { ( [HTTP::method] == "PUT" ) } {
        switch -- -glob ${URI} {
            "/x/*" -
            "/y/*"
            {
                pool PUT_X_Y
            }
        }
    } elseif { ( [HTTP::method] == "POST" ) } {
        switch -- -glob ${URI} {
            "/x/*"
            {
                pool POST
            }
        }
    }
    default {
        pool POOL1
    }

}
