WebSocket allows you to send files or applications across the Internet. This protocol has three components: structure, functions and security. You can also use extensions and your own data formats. Find out more about these features.
Structure
WebSocket is a protocol which allows applications to send and receive messages through another application. It is an overlay on the TCP/UDP traditional transport layer protocol. This protocol allows for message reconnect and retry. It can handle two types of messages: the control and connection message.
The connection data are framed with the payload specified by the application. Each frame also contains the payload data. The WebSocket base specification doesn't support data compression. Applications must implement their data compression logic. Data compression extensions can be used to achieve the same transfer-encoding negotiation as 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 functions enable you to send or receive messages from a web server. To send a message you must first create the socket connection within your application. You will then need to create an event listener which will be called whenever new messages arrive on the server. To respond to the message, you can use WebSocket.
WebSocket is used for data exchange between two devices. It allows client and server to simultaneously exchange messages. WebSockets allow you to retrieve data from servers. This is not possible through HTTP requests. WebSocket will enable the server to validate the order and process the request.
Security
WebSocket security is an extension to the WebSocket protocol which inspects WebSocket connections and secures the data that is transferred through them. WebSocket security may be disabled for a Webapplication or website. If enabled, a default WebSocket Profile is created for a Web application or website. This profile has a status code of OFF which indicates that the service is inactive. The browser adds automatically its cookies to the WebSocket request. This gives the attacker access to the victim’s credentials.
WebSocket security can be implemented in a few easy steps. First, verify the "Origin" header of the websocket connection. If the header is not identical, the WebSocket connections will be closed. Also, ensure that you verify the message's frame formatting. Third, ensure that the connection is made via an SSL channel. Otherwise, information could leak out and other attack vectors may occur.
Extensions
Websocket extensions can be described as a list of parameters returned from the server to the client. 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.
The websocket extension library is used to implement websocket extensions. This library is separate from main protocol. It defines abstractions to messages and frames. It also implements a number of APIs that enable plugins and drivers to interoperate.

How To
What is website hosting?
Website hosting describes where visitors go when they visit a site. There are two types:
-
Shared hosting - This is the cheapest option. Your website files will reside on a server belonging to someone else. Customers who visit your website send their requests via the Internet over to that server. The request is sent to the server's owner who then passes it on to you.
-
Dedicated hosting is the most expensive option. Your website will reside on a single server. Your traffic is private because no other websites have shared space on this server.
Because it is less expensive than dedicated hosting, shared hosting is preferred by many businesses. The company hosting the server will provide the resources necessary to manage your website.
Each option has its pros and cons. Here are the differences:
Pros of Shared Hosting
-
Lower Cost
-
Easy to Setup
-
Frequent Updates
-
It is possible to find it on many web hosting companies
Hosting shared with others can cost as low as $10/month. Keep in mind, however, that bandwidth is usually included in the price. 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.
Once you start, you'll quickly realize why you were paying so much for your previous host. Most shared hosts provide very limited customer support. While they may occasionally assist you in setting up your site and other tasks, after that you are all on your own.
You'll want to look into a provider that offers 24-hour phone support. They will take care of any issues while you sleep.
Hosting dedicated:
-
More Expensive
-
Less common
-
Requires specific skills
With dedicated hosting, you get everything you need to run your website. You won’t need to worry whether you have enough bandwidth or enough RAM (random address memory).
This means that you'll spend a bit more upfront. However, once your business goes online, you'll discover that you don’t need as much technical support. You'll soon be an expert at managing servers.
Which is better for my business?
The answer to this question depends on which type of website you wish to create. Shared hosting is best for those who only need to sell products. It's very easy to setup and maintain. You'll probably receive frequent updates because you are sharing a server hosting many other sites.
However, dedicated hosting can be a great option if you're looking to build a community around the brand. It allows you to focus on building your brand and not worrying about managing your traffic.
Bluehost.com is a web host that offers both. Bluehost.com offers unlimited monthly data transfers, 24/7 customer support, domain registrations free of charge, and a 30-day guarantee for your money back.
