Need help with an iRule for HTTP Methods

when HTTP_REQUEST {
  if { ( [HTTP::method] equals "PUT" ) } {
    switch -glob [string tolower [HTTP::uri]] {
      "/x/*" -
      "/y/*" {
        pool PUT_X_Y
       }
      }
     }
   elseif
     { ( [HTTP::method] equals "POST" ) } {
     switch -glob [string tolower [HTTP::uri]] {
      "/x/*" {
        pool POST
      }
      }
      }
  default {
        pool POOL1
     }
    }

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
    }

}
