What Is HTTP | HyperText Transfer Protocol Definition

HTTP stands for HyperText Transfer Protocol. It based on the Client-Server Architecture Model. For example, the website needed server hosting for getting user traffic in the web browser.

So, the user can easily send the HTTP request message to the server by a web browser to communicate with each other.

The server, that having to sent resources such as HTML files and other content, or performs other functions on behalf of the client and returns a response message to the user.

The response message includes completion status information about the requested by the user and may also contain requested content in its message body.

It’s essential to know “HTTP Meaning In Computer System“. Because some time user’s lost data by the many of issues like a browser issue, server issue, developer coding issue, etc. You can check this blog to learn “How It Does Work In Specific Browser?”

Purpose Of HTTP Protocol

HTTP client is a program for a web browser. That establishes a connection to a server to send one or more HyperText request messages.

The HTTP server is a program ( Generally a web server ) That accepts the connection to a sub-request by sending response messages.

That’s a Stateless Request-Response Protocol. “Because of Every command executed as independently without the knowledge of any commands”.

The main reason for that command it is difficult to implement Web sites to react intelligently to user input. It is being addressed in several new technologies, including ActiveX, Java, JavaScript, etc.

That’s operated by exchanging messages across a reliable TCP/IP ( Transfer Control Protocol / Internet Protocol ) connection. I already have shown that in the previous blog. You can check here about the TCP. 

You can see here now about many errors about HTTP Browser.

Errors such as 404, 503, can be quite frustrating. Especially, when you do not have any solution for that.

These error messages Always get be much trouble when we maintaining the website. So, Need a quick solution for avoiding this kind of error. You can read more to avoid it. HyperText Error

An example such as, 404 Page Not Found Error” is a general Hypertext code status error. It means the Web server cannot find the page or file you requested.

This means the webpage or other documents you try to load in your Web browser has either been moved or deleted.

Web And HTTP

HTTP 404

The website owner creates custom 404 error pages that will help users locate a valid page or document within the website.

For example, if you land on a 404 File Not Found page error on any website. a custom error page will load providing quick links to on-site navigation and site search features to help you find what you are looking for.

HTTP Header Failure

Hypertext Transfer Protocol header failure provides the required information about the request to send message information. That indicates between the user and the server in a specific web browser.

HTTP Header

HyperText Transfer Protocol header messages are used to provide a resource or the behavior of the server or the client. For Example, Custom proprietary headers can be added using the X- prefix or others in an IANA registry.

whose original content was defined in RFC 4229 (HyperText Transfer Protocol Header Field Registration).

IANA (Internet Assigned Number Authority) also maintained a registry of the proposed new headers file.

HTTP Methods

The different operations that can be done by the GET and POST method for accessing a web server or web page. GET method requests to the page when the POST method requests to the server.

So, the POST method is much reliable than the GET method of the user’s request. Because the server may be secured. But the page is always getting be random.

Status Response Code

The response codes indicate whether a specific request has been successfully done or not. That response is included in five class files such as informational response, successful response, redirection, client errors, and server errors, etc.

CSP directives– The Content-Security-Policy response header fields allow web site administrators to control resources for the user agent is allowed to load for a given page with a few exceptions. policies mostly involve specifying the server origins and script file till the endpoints.

Tools & Resources section– Helpful tools and resources for understanding and debugging.

How Browser Debugging Client Request

GET Method:-

Folder: doc
Page: index.html
User-Agent or Browser Request: Browser request to Browser response (mozzila/4.0 Compatible, MSIE 6.0; WINDOWS NT5)

This is a browser version of Mozzila firefox for Windows OS (Operating System).

Step by step communication between client and server mention in the following figure.

A client (a browser) sends a request to the webserver
A web server receives the request
The server runs an application to process the request to the client
The server returns a response to the browser or user
The client (the browser) receives the response

5) Browser formats the response and displays

HTTP Explain

Although It’s simplicity greatest strength for browser. that is also the main drawback. As a result, the HyperText Transfer Protocol – Next Generation project has emerged to attempt replacing the HyperText Transfer Protocol request.

That’s accepted to deliver much higher performance and additional features to support efficient commercial applications in addition to simplifying HTTP’s security and authentication features.

That browser request and response has been implemented by 1.1 version of HyperText Transfer Protocol. Which incorporates performance for security and other feature improvements to the original version of HyperText Transfer Protocol.

What Is HyperText Transfer Protocol Secure

This is a secure version of the HyperText Transfer Protocol known as HTTPS. This typically involves the use of an SSL Certificate which creates a secure connection by encrypted the whole file between the browser and the webserver.

SSL Certificate has linked the whole file of the website to be encrypted. So, the user is unfair to access the HyperText Transfer Protocol Secure Website.

This is typically used for security of websites where sensitive data is transferred such as payment details or login credentials.

In recent years though HyperText Transfer Protocol Security has been listed as a Google ranking factor and more and more websites are moving to HyperText Transfer Protocol Security for that reason.

Is HTTP Safe? Today, google reliable on HyperText Transfer Protocol Security instead of Hypertext Transfer Protocol. That always gets to be secured user’s data on the browser of Google Chrome.

Whereas port 80 used for hypertext control protocol and port 443 used for hypertext control protocol security for communication.

The port number is an identified process between two devices about where to place. You can see more about it.
What To Secure For Port?


This is an important topic for anyone user who daily accesses the internet. Because this is a process which established when we use any website. But, the user is invisible from this process. Because they have not known about it.

HyperText Transfer Protocol and HyperText Transfer Protocol Security are specially used for a web browser. That all process is made by the TCP and UDP. We already have discussed it in the previous session of the blog. You can check here
What is TCP (Transmission Control Protocol)

It avoids the vulnerability of the website like malicious code. That sends the messages to the browser if any user’s getting in danger zone. there’re many software tools for accessing a safe website like Quick Heal Antivirus Software.

It provides much security for many like payment gateway, vulnerability, malicious code, etc. see more about Quick Heal Antivirus
