Q in Protocols

[veena madhukar]

HTTP is Stateless, non transactional, Connection based protocol.
HTTPS is Stateful, Connection based protocol. Is HTTPS transactional?

Also, can you explain what does Connection based means?

[Prasanna Sudharshan]

HTTP Connection based ? HTTP is a request/response protocol between clients and servers. An HTTP client, such as a web browser, typically initiates a request by establishing a Transmission Control Protocol (TCP) connection to a particular port on a remote host (port 80 by default. An HTTP server listening on that port waits for the client to send a request string, such as "GET.

For this reason it is called as connection based.To know more about connections in HTTP, hit www.w3.org/Protocols/rfc2616/rfc2616-sec8.html

HTTP Transactional? Transaction in its simplest term would mean - performing one or more jobs , as a single unit. Hence there is no question of HHTP being transactional.

Veena,
Https is "secure hypertext transfer session with the specified site address"

As such it has all the properties of HTTP along with the security factor.This security is implemented using SSL(secure socket layer) which is an encryption protocol invoked on a Web server.

With this introduction to HTTPS do you think it should be transactional?

Hi,

According to HTTP 1.1 - HTTP is connection based
HTTP 1.0 - HTTP is connection less

Which is for the SCEA exame?

Please clarify

Thanx
