5
Q
- The preferred submission method of forms: appends the data to the URL
- Data sent by this method is attached to the request as a query string, so may be visible in the browser’s address field in the web server’s response.
- They only allow the URL to append up to around 200 characters ( varies by browser)
A
GET
6
Q
- Submission method of forms that encodes the data differently from the GET method.
- Can be used when the GET method fails.
- You can submit by the POST method to prevent sensitive data from being visible in the browser’s address field with the web server’s response.
- Provides a much larger capacity than the GET method as the text is sent as “Form Data” along with the HTTP header, not simply appended to the URL.
A
POST
