<postfield> tag - The postfield tag is used to set a name/value pair that can be transmitted to 
an origin server (source of the request) during a URL request. The name is set by the name 
attribute and must be a valid WML variable name. The value is set by the value attribute. There 
are no visual rendering implications with this tag.

■

<go> tag - The go element can contain one or more postfield elements. If the destination of a 
go element is a card within the same deck, all of the postfield elements will be ignored. The go 
element can also contain one or more setvar elements. Unlike postfield elements, there are no 
destination limitations on passing information contained in the setvar elements. The <go> 
nested tags (postfield and setvar) are supported.

method

post
get

Sets how to send the data to 
the server. Default method is 
get. When method="get", the 
data is sent as a request 
with?data appended to the 
URL. The disadvantage of get 
is that it can be used only for a 
limited amount of data; if you 
send sensitive information it 
will be displayed on the screen 
and saved in the web server's 
logs.With method="post", the 
data is sent as a request with 
the data sent in the body of 
the request. This method has 
no limit, and sensitive 
information is not visible.
