POST is more secure than GET for a couple of reasons. GET parameters are passed via URL. This means that parameters are stored in server logs, and browser history. When using GET, it makes it very easy to alter the data being submitted the the server as well, as it is right there in the address bar to play with.
Is put Update?
No, PUT is not for update or create. It is for replacing. Note that you can replace nothing with something for the effect of creating.
Why put method is used?
The PUT method requests that the enclosed entity be stored under the supplied URI. If the URI refers to an already existing resource, it is modified and if the URI does not point to an existing resource, then the server can create the resource with that URI.
Which is safer get or POST?
GET is less secure than POST because sent data is part of the URL. POST is a little safer than GET because the parameters are stored neither in the browser history nor in the web server logs.
Is put idempotent?
The difference between PUT and POST is that PUT is idempotent: calling it once or several times successively has the same effect (that is no side effect), whereas successive identical POST requests may have additional effects, akin to placing an order several times.
Why POST method is not safe?
Since POST is not a idempotent method, calling it multiple times can result in wrong updates. What would happen if you sent out the POST request to the server, but you get a timeout.
Can a PUT request have a body?
If the request has a Content-Length header, then it has a body. It may be an empty body, but still a body. In contrast to a request with no Content-Length header, which has no body at all, not even an empty one. So yes, a PUT request, technically, strictly, has to have a body.
What should I reply PUT request?
Generally, when a PUT request creates a resource the server will respond with a 201 ( Created ), and if the request modifies existing resource the server will return a 200 ( OK ) or 204 ( No Content ).
What should a put return?
PUT should never return a body, but must return a response code in the header. Just choose 200 if it was successful, and 4xx if not. There is no such thing as a null return code.
Is POST Body secure?
Yes, POST is better than GET because POST data is not usualy logged by a proxy or server, but it is not secure. To secure a password or other confidential data you must use SSL or encrypt the data before you POST. Another option would be to use Digest Authentication with the browser (see RFC 2617).
What is the difference between GET and POST in HTML?
The GET and POST method are used for sending the data to the server, and the main difference between them is that GET method append the data to the URI defined in the form’s action attribute. Conversely, POST method attaches data to the requested body.
Should login be get or POST?
If your login request is via a user supplying a username and password then a POST is preferable, as details will be sent in the HTTP messages body rather than the URL. Although it will still be sent plain text, unless you’re encrypting via https.
