  • POST : Requests that the server accept the entity enclosed in the request as a new subordinate of the web resource identified by the URI. The data POSTed might be, as examples, an annotation for existing resources; a message for a bulletin board, newsgroup, mailing list, or comment thread; a block of data that is the result of submitting a web form to a data-handling process; or an item to add to a database.

  • In computing, POST is one of many request methods supported by the HTTP protocol used by the World Wide Web. The POST request method is designed to request that a web server accept the data enclosed in the request message's body for storage. It is often used when uploading a file or submitting a completed web form.

    In contrast, the HTTP GET request method is designed to retrieve information from the server. As part of a GET request, some data can be passed within the URI's query string, specifying for example search terms, date ranges, or other information that defines the query. As part of a POST request, an arbitrary amount of data of any type can be sent to the server in a request message body. A header field in the POST request usually indicates the message body's Internet media type.
