Transactions - jude-lindale/Wiki GitHub Wiki

Let’s look in more detail how clients use HTTP to transact with web servers and their resources. An HTTP transaction consists of a request command (sent from client to server), and a response result (sent from the server back to the client).

Methods

HTTP supports several different request commands, called HTTP methods . Every HTTP request message has a method. The method tells the server what action to perform (fetch a web page, run a gateway program, delete a file, etc.).

Status Codes

Every HTTP response message comes back with a status code. The status code is a three-digit numeric code that tells the client if the request succeeded, or if other actions are required.
