    • validMethod

      public static boolean validMethod(byte[] bytes, int offset, int length)
      Checks that the first length bytes in the given byte array, starting at offset, represent a valid HTTP request method string.
      Parameters:
      bytes - The byte array
      offset - The index to start at
      length - The number of bytes to check
      Returns:
      true if the given bytes represent a valid HTTP request method string
