The Hypertext Transfer Protocol, or HTTP for short, is the backbone of the Internet. Under this umbrella, HTTP responses and requests play a critical role. It starts right after a client wants to communicate with an HTTP server. After that, it must create and send an HTTP request to the website or web server. Then, the server receives the request, creates an appropriate HTTP response, and sends it back to the client. <\/p>\n\n\n\n

We are here to provide comprehensive HTTP protocol content for you in today’s guide. First, we will briefly explain what HTTP is. Second, we will introduce important HTTP requests, including GET, PUT, DELETE, POST, HEAD, TRACE, and PATCH. After that, when a client sends a request to the web server, it will get an HTTP response code; There are dozens of them, but we should, and we want to focus on the most used ones, such as 100 \u2013 Continue, 102 \u2013 Processing, 200 \u2013 Ok, 400 \u2013 Bad Request or 404 \u2013 Not Found. Of course, there are some requirements to send and receive appropriate HTTP responses and requests; We will also list them for you at the end of our article. So, without further ado, let\u2019s start! <\/p>\n\n\n\n

<\/span>What Is Hypertext Transfer Protocol (HTTP)? <\/span><\/h2>\n\n\n\n

Before diving into our topic, we briefly mention HTTP, the most widely used protocol worldwide. The protocol enables the transfer of information or data across the Internet. A little bit hard to understand, isn’t it? Well, let us explain it more understandably. HTTP is the fundamental method of communication between web users and servers that host websites. Regardless of which browser you use on the web, when you type the domain name of a website and click on the related link, the browser automatically adds HTTP at the beginning of the site address when the site opens. So, HTTP identifies how information is accessed, transferred, and displayed and how to act when a specific command is received.  <\/p>\n\n\n\n

HTTP messages consist of two things: a header and a body. From this two-part, the body may only sometimes be present. The body part contains the data that needs to be sent over the network based on the instructions in the header. On the other side, the header includes some vital information, such as encoding details. In the case of a request, the header will also contain relevant HTTP types (We will mention them below).  <\/p>\n\n\n

<\/span>HTTP Requests Types <\/span><\/h2>\n\n\n\n

HTTP requests, also known as HTTP methods or HTTP verbs, are the methods that are in use to specify what the client wants to do and for what purpose they want to connect to the resource.  <\/p>\n\n\n\n

Now, we will list seven common types of requests. <\/p>\n\n\n\n

GET<\/h3>\n\n\n\n

GET is the most basic form of the request method, which is in use for data flow from the web server to the web browser. In other words, GET is for retrieving data from a web server. It’s like when you click a link or enter a specific URL into the navigation bar; browsers use the GET method each time. It commands the server to send the data identified by the web address to the client. Once the client gets the data, they can perform any action. <\/p>\n\n\n\n

GET is in use to access an existing resource on the server. The most crucial advantage of GET is that you can send query text in the URL, modify and resend the data and even resend the previous requests. However, URLs displayed on the screen may lead to a problem in terms of security. Therefore, you should not send essential and private information via GET.  <\/p>\n\n\n

\n
\"HEAD\"<\/figure><\/div>\n\n\n

HEAD<\/h3>\n\n\n\n

HEAD is very similar to the GET method. This method requests the headers from the server in a similar way as if the document was secure after using the GET method. The only visible difference between these methods is that the HEAD method of HTTP does not contain any response body, unlike the HTTP GET method. <\/p>\n\n\n\n

PUT<\/h3>\n\n\n\n

PUT is in use for creating or updating\/modifying an existing source(s) identified by the corresponding URL. This method is for when the server-side action should be repeated if the request is sent again.  <\/p>\n\n\n\n

DELETE<\/h3>\n\n\n\n

Delete is in use to remove or delete the data\/resource in a specific server location. We can briefly say that DELETE is the opposite of PUT.  <\/p>\n\n\n

\n
\"POST\"<\/figure><\/div>\n\n\n

POST<\/h3>\n\n\n\n

POST is in use to send data to the web server. With this method, you can send request parameters in the message body and the URL. Browsers will ask if you would like to resend the parameters in the message body of the POST request when you press the back button. The main reason for it is to prevent accidental duplicate transactions. Therefore, we recommend using the POST method when performing an important and private transaction. <\/p>\n\n\n\n

PATCH<\/h3>\n\n\n\n

PATCH is in use to modify or replace a part of the resource you want to update. For instance, you can prefer the PATCH method when you only need to update one part of a resource.  <\/p>\n\n\n

\n
\"TRACE\"<\/figure><\/div>\n\n\n

TRACE<\/h3>\n\n\n\n

TRACE is in use to detect all points that the request sent to the server from the client until it reaches the server. Therefore, TRACE helps you understand the changes made during requests from the main source. If a proxy server is in use between the server and the client, TRACE can also be in service to detect the corresponding server and the changes made on the request. <\/p>\n\n\n\n

There are some essential differences between these HTTP requests. For example, (PUT vs. PATCH) Put is in use to replace the resource on the server with a new one, while PATCH is in service to change a part of the existing resource. For instance, let’s say when you only need to update one part of the resource; using the PUT method may not be inefficient. Or, (PUT vs. POST) If a PUT request is repeatedly sent, the outcome will remain constant, but the results the client will receive vary if a POST request is repeated. <\/p>\n\n\n\n

<\/span>HTTP Response Codes <\/span><\/h2>\n\n\n\n

After each request, the client will receive a response code with a different meaning. Each code consists of 3 digits, mainly to indicate whether the client’s request message has been successful. <\/p>\n\n\n\n

After examining the most used HTTP request methods, it’s time to learn HTTP status codes. Let’s dive in! <\/p>\n\n\n\n

HTTP response status codes are grouped into five distinct categories. The first digit of the code points out the category of response, whereas the last two digits of the code do not indicate any particular function. <\/p>\n\n\n
