  • single transaction per connection:
  • stateless nature of the connection: end-user's previous connection run-time input will not be seen by current connection
client & server open the connection --->
client sends request messages to server --->
server locates requested information and sends
response back to client ----> client & server close the connection (note each URL represents a separate connection process)
