Basic features in HTTP protocol -- a client-server model:
-
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 requested back to client ----> client & server close the connection (note each URL accessed represents a separate connection process)
