What is the difference between get and post method in HTTP?
- All the name value pairs are submitted as a query string in URL.
- It's not secured as it is visible in plain text format in the Location bar of the web browser.
- As the data transfers through address bar (URL) there are some restrictions in using space, some characters like ampersand (&) etc in the GET method of posting data. We have to take special care for encoding data if such special characters are present.
- Length of the string is restricted.
- If method is not mentioned in the Form tag, this is the default method used.
- If get method is used and if the page is refreshed it would not prompt before the request is submitted again.
- One can store the name value pairs as bookmark and directly be used while sharing with others - example search results.
- Data is always submitted in the form of text
- If the response of the page is always same for the posted query then use GET example database searches
- All the name value pairs are submitted in the Message Body of the request.
- Length of the string (amount of data submitted) is not restricted.
- Post Method is secured because Name-Value pairs cannot be seen in location bar of the web browser.
- If post method is used and if the page is refreshed it would prompt before the request is resubmitted.
- If the service associated with the processing of a form has side effects (for example, modification of a database or subscription to a service), the method should be POST.
- Data is submitted in the form as specified in enctype attribute of form tag and thus files can be used in FileUpload input box.
GET and POST methods are both ways of transporting variables (and their values) from one page to another. However, they transport the variable names and values in different ways. GET uses the URL to transfer variables. Web pages can pick up the URL address and detach the variables usable to the scripting language used in the page. A user can change the variable names and values of a URL with GET-type variables. This introduces security risks, as it is an open way to attack a website. All variables that could possibly be input by a user should always be checked. GET values must be under 255 characters, otherwise some older browsers will not transfer values properly. Today's browsers propagate values just fine with larger character limits, such as 4,000 - but caution should be taken. POST transfers variables from one page to the next - broadly speaking - silently. No users can edit these variables without simulating a POST transfer to the page - which is a more difficult route for site attackers to make. These variables should still always be checked. POST values can be of infinite length.
The difference between a GET and a POST is the way data is transferred to a servlet. With a GET, the URL will show each name/value pair on the query string in the URL. For example, if you had a form with a field named 'foo,' and when submitted had a value of 'bar,' the URL might be something like this: http://www.example.com/servlet?foo=bar With a POST, this information is not visible in the URL. Instead, it…
If the HTTP request method is POST, the user submitted data is in the Request.Form() collection If the HTTP request method is GET, then user submitted data is in the Request.QueryString() collection However, you can still do: <form method="post" action="page.asp?data=value"> <input type="text" name="txtName" value="Name"> </form> and Request.Form("txtName") will contain "Name" -and- Request.QueryString("data") will contain "value"
As per functionality both GET and POST methods were same.Difference is GET method will be showing the information information to the users.But in the case of POST method information will not be shown to the user. The data passed using the GET method would be visible to the user of the website in the browser address bar but when we pass the information using the POST method the data is not visible to the user…
1) HTTP GET: In HTTP GET method data passed through URL querystring using name value pair. It's simpler and you can troubleshoot any problems simply by looking at the address bar in your browser because all values passed are displayed there. This is also the primary weakness of this method. 2) HTTP POST: In HTTP POST request data are embeded in a HTTP HEADER. So data are NOT visible to end user while you can…
// get <html> <body> <form name="input" action="form_action.asp" method="get"> First name: <input type="text" name="FirstName" value="Mickey" size="20" /><br /> Last name: <input type="text" name="LastName" value="Mouse" size="20" /><br /> <input type="submit" value="Submit" /> </form> <p>Click the "Submit" button and the input will be sent to a page on the server called "form_action.asp".</p> </body> </html> //post The form-data can be sent as URL variables (with method="get") or as HTTP post (with method="post"). Notes on the "get" method: This method…
doPost() is the method in the servlet that is used to service the Http requests submitted using the Post option. HTML forms can be submitted in two ways using the Get method and the Post method. You can specify the method while declaring the form itself. So you will have two methods in the servlet doGet() and doPost() each for one of them

$_POST and $_GET are both PHP functions used to extract input from HTML forms. However, the difference is that $_POST keeps the extracted variables hidden from users, whereas $_GET does not. Because of this, there is a major difference between the two functions in terms of security. Why would you use $_GET at all, then? Because some websites have large databases full of information for the user. For example, say you were shopping online, and…
What is the difference between the first past the post voting system and the proportional representation voting system?
Actually, both are the ways of traveling the data from client machine to server machine.But the difference is that data will travel through GET as a query_string and through POST as a input_string. *Length of query_string is 256 but the length of input_string is unlimited. *GET is fast as compare to POST. *GET is visible POST is invisible.
