GET VS POST FULL

Keys and values are both escaped by replacing spaces with the '+' character and then using percent-encoding on all other non- alphanumeric characters. When a web browser sends a POST request from a web form element, the default Internet media type is ' application/x-Each key-value pair is separated by an '&' character, and each key is separated from its value by an '=' character. In these cases, HTTP POST should be used.

Even if HTTPS is used, preventing the data from being intercepted in transit, the browser history and the web server's logs will likely contain the full URL in plaintext, which may be exposed if either system is hacked. Equally, HTTP GET should not be used where sensitive information, such as usernames and passwords, have to be submitted along with other data for the request to complete. Percent-encoding of reserved characters in URLs and query strings can significantly increase their length, and while Apache HTTP Server can handle up to 4,000 characters in a URL, Microsoft Internet Explorer is limited to 2,048 characters in any URL. Browsers and web servers can have limits on the length of the URL that they will handle without truncation or error. An example of this is when a great deal of data would need to be specified in the URL. There are times when HTTP GET is less suitable even for data retrieval. Search forms, for example, are ideally suited to having method='get' specified. Many forms are used to specify more precisely the retrieval of information from the server, without any intention of altering the main database. That is not to say that every web form should specify method='post' in its opening tag. With regard to the second point, it is possible to use client-side scripting, or to write standalone apps, to make use of the other HTTP methods where they are relevant, but outside of this most web forms that submit or alter server data continue to use POST for the purpose. Web application frameworks such as Ruby on Rails and others make it easier for designers to provide their users with semantic URLs. Secondly, given most web browsers' natural limitation to use only GET or POST, designers felt the need to re-purpose POST to do many other data submission and data management tasks, including the alteration of existing records and their deletion.Įfforts by some influential writers to remedy the first point began as early as 1998. In fact, unless some effort is made, the last part of a URI will more likely describe the web application's processing page and its technology, such as.

First, there is no technical reason for a URI to textually describe the web resource subordinate to which POST data will be stored. Early website designers strayed away from this original concept in two important ways. For example, for the URI, POST requests might be expected to represent new customers, each including their name, address, contact details and so on.

POST's place in the range of HTTP methods is to send a representation of a new data entity to the server so that it will be stored as a new subordinate of the resource identified by the URI.

Web browsers normally use only GET and POST, but RESTful online apps make use of many of the others.

The world wide Web and HTTP are based on a number of request methods or 'verbs', including POST and GET as well as PUT, DELETE, and several others.
