HTTP GET and POST requests
• In HTML, one can specify two different submission methods for a form. The method is specified inside a FORM element, using the METHOD attribute.
• The difference between METHOD="GET" (the default) and METHOD="POST" is primarily defined in terms of form data encoding. The official recommendations say that "GET" should be used if and only if the form processing is idempotent, which typically means a pure query form. Generally it is advisable to do so.
• Problems related to long URLs and non-ASCII character repertoires which can make it necessary to use "POST" even for idempotent processing.
• The Get is one the simplest Http method. Its main job is to ask the server for the resource.
• If the resource is available then it will given back to the user on your browser. That resource may be a HTML page, a sound file, a picture file (JPEG) etc.
• We can say that get method is for getting something from the server. It doesn't mean that you can't send parameters to the server. But the total amount of characters in a GET is really limited.
• In get method the data we send get appended to the URL so whatever you will send will be seen by other user so can say that it is not even secure.
• The Post method is more powerful request. By using Post we can request as well as send some data to the server.
• We use post method when we have to send a big chunk of data to the server, like when we have to send a long enquiry form then we can send it by using the post method.
