| GET
|
An HTTP request method.
Information from a form using the GET method is appended onto the
of the action URI being requested. Your CGI program will receive
the encoded form input in the environment variable QUERY_STRING.
The GET method is used to ask for a specific document - when you click
on a hyperlink, GET is being used. GET should probably be used
when a URL access will not change the state of a database (by, for
example, adding or deleting information) and POST should be used when
an access will cause a change.
Many database searches have no visible
side-effects and make ideal applications of query form using GET.
