GET vs POST:

GET :

• name value pairs are transported from page to page in the url string, you can see the variables right in the address bar of the browser.
• Less secure way of transfering sensitive data. All variables are in plain sight of any user
• has a character limit of 255, (including spaces).

POST:

• Can transfer larger amounts of data from page to page.
• name value pairs are transfered from page to page in the "header" section of the web page. (not in plain sight)
• More secure way (but not totally safe at all!)
