Comparision between SMTP and HTTP
SMTP
|
HTTP
|
Transfer files (eg;email messages) from one mail server to
another mail server
|
Transfers files from web server to web user agent (ie. The
browser)
|
Push protocol: the sending mail server pushes the file to
the receiving mail server. In particular, the TCP connection is initiated by
the machine that wants to send the file.
|
Pull protocol: someone loads information on a web server
and users use HTTP to pull the information offthe server at their
convenience. In particular, the TCP connection is initiated by the machine
that wants to receive the file.
|
Requires each user message, including the body of each
message to be in 7 –bit ASCII format. If the message contains that are not
7-bit ASCII, then the message has to be encoded into 7-bit ASCII
|
Do not impose this restriction
