The WebSocket protocol is used to send files, applications, or data over the Internet. This protocol has several components: a structure, functions, and security. It also supports extensions, and lets you use your data formats. Learn more about these features.
Structure
WebSocket allows an application to send and get messages from another application. It is added to the TCP and UDP transport layer protocols. This protocol allows for message reconnect and retry. It works with two types message, the control message as well as the connection.
The connection data are framed with the payload specified by the application. Each frame also contains the payload data. Data compression is not supported by the WebSocket standard, so applications will need to implement their own data compression logic. Data compression extensions enable the equivalent of transfer-encoding negotiation found in HTTP. These extensions can be listed in the Upgrade handshake and can be selected by the server for the lifetime of the connection.
Functions
Websocket lets you send and retrieve messages from a remote server. First, create a socket in your application. Next, create an event listener to be called when a new message arrives at the server. Then, you can use the WebSocket function to respond to the message.
WebSocket is used to send and receive data between two devices. It allows the client to send and receive data simultaneously from both servers. WebSockets can be used to fetch data from a server. This is not possible using HTTP requests. The server will have to check the order and then process the request, but it will do so through WebSocket.
Security
WebSocket Security is an extension of the WebSocket protocol that inspects WebSocket connection and protects data being transmitted through them. WebSocket security may be disabled for a Webapplication or website. A default WebSocket profile for a website or web application is created when enabled. This profile has a status OFF, meaning that the service's inactive. Also, the browser automatically adds its cookies the WebSocket handshake request. This means that attackers have access to victim's credentials.
WebSocket Security is quite simple to set up and can be accomplished in just a few steps. First, verify the "Origin" header of the websocket connection. If the header does not match, the WebSocket connection will be closed. Second, be sure to check the message's frame format. And third, make sure that the connection is being made over an SSL channel. If not, information can leak out and other attack vectors can occur.
Extensions
Websocket Extensions are a collection of parameters returned by the server. These are specified in the "Sec-WebSocket-Extensions" header and must be implemented by both the client and the server. The server is responsible to activate the extensions and return them to clients.
Websocket extensions work with the websockets-extensions library. This library is independent from the main protocol and defines abstractions of messages and frames. It implements a variety of APIs which enable drivers and plugins interoperate.

What is website hosting?
Website hosting is the location where people go when they visit websites. There are 2 types.
-
Shared hosting - This is the cheapest option. Your website files reside on a server controlled by someone else. Customers who visit your website send their requests via the Internet over to that server. The request is then handed to the owner of that server.
-
Dedicated hosting – This is the most expensive option. Your website is hosted entirely on one server. There are no other websites sharing space on the server. Your traffic remains private.
Shared hosting is cheaper than dedicated hosting for most businesses. You can use shared hosting if the company owns the server to provide the resources required for your website.
But there are pros and cons to both options. Here are the differences:
The pros of shared hosting:
-
Lower Cost
-
Easy to Setup
-
Frequent Updates
-
It can Be Found On Many Web Hosting Companies
Shared hosting can often cost as little as $10/month. Remember that shared hosting usually comes with bandwidth. Bandwidth is how much data you can transfer to the Internet. So even if you only upload photos to your blog, you may still pay extra money for high amounts of data transferred through your account.
You'll soon realize why your old host cost so much once you get started. Most shared hosts don't offer any customer support. While they may occasionally assist you in setting up your site and other tasks, after that you are all on your own.
It is important to find a provider that provides 24-hour support. They will help you deal with any issues that arise while your sleeping.
Hosting dedicated:
-
More Expensive
-
Less Common
-
Specific Skills Required
With dedicated hosting, all you need to maintain your website are provided. You won’t need to worry whether you have enough bandwidth or enough RAM (random address memory).
This means you will need to spend more upfront. Once you get started with your online business, you will find that you don't require much technical support. You'll become an expert at managing your servers.
Which Is Better for My Business?
The answer will depend on the type and purpose of your website. Shared hosting is best for those who only need to sell products. It's easy to set up and maintain. A server shared with several other sites means that you will receive frequent updates.
If you want to create a community around a brand, dedicated hosting may be the best choice. Instead of worrying about your traffic, you can build your brand while still being able to concentrate on your business.
