| 10.22.2.Form Submission 101: GET Versus POST |
|
|
FORM's METHOD can be set to either GET or POST. |
GET, which is the default setting, passes the form values on the URL. |
The following simple form can be used as an example. |
<FORM ACTION=http://www.java2s.com METHOD=GET>
<SELECT NAME=STATE>
<OPTION VALUE=NC>North Carolina</OPTION>
<OPTION VALUE=SC>South Carolina</OPTION>
<OPTION VALUE=CA>California</OPTION>
</SELECT>
<INPUT TYPE="button" VALUE="Submit">
</FORM>
|
|
When POST is used, the browser contacts the URL specified in the ACTION property and sends the data in the body of the HTTP request. |
If you are sending large amounts of form information to the server, the POST method should be used. |
The POST method is also useful for keeping your data from being easily seen. |
