HTTP Status codes

-

Just kidding...

 Have you ever come across this message when you try to access a certain web page? Ever wondered what 404 stands for?

In this mini blog we are going to look at some widely used status codes in HTTP.

Types of HTTP Status codes

  • 1xx : Informational Status code. These codes keeps the client informed of basic headers.
  • 2xx: These codes reflect a successful response or operation
  • 3xx: Redirection codes
  • 4xx: Client Error codes (404)
  • 5xx: Server Error codes
Now, we'll look at some commonly used status codes.

2xx

200 - OK

  • Standard response for successful HTTP requests. The actual response will depend on the request method used. In a GET request, the response will contain an entity corresponding to the requested resource. 

201 - Creat

  • This status code is sent as a response when the request was a POST method. If the POST request was successfully sent and processed, we get a 201 status code.

204 - No Content

  • The request was successful but there's nothing to respond with. Hence, this status code will be returned. This status code was widely used in the early days of HTTP implementation and losing its fame recently.

3xx

301 - Moved Permanently

  • This status codes indicates that all resources are moved to a different location and all current and future request requests will be redirected to that new location

302 - Moved Temporarily (also known as Found)

  • The requested resource was found but has been moved temporarily to another location.

4xx

400 - Bad request

  • The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax, size too large, invalid request message framing, or deceptive request routing)

401 - Unauthorized (Same as 403)

  • This status code is used  when authentication is required and has failed or has not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. 

404 - Not Found!

  • The requested resource cannot be found on the URL/URI. There are also substatus codes defined by Microsoft Internet Servers. See it here.

408 - Request timed-out

  • The server timed out waiting for the request. That is the client did not send any request during the given period to make requests

409 - Conflict

  • Indicates that the request could not be processed because of conflict in the current state of the resource, such as an edit conflict between multiple simultaneous updates.

5xx

500 - Internal Server Error

  • This status code is sent when an unexpected or unknown error occurred in the server while making a request.

502 - Bad Gateway

  • The server was acting as a gateway or proxy and received an invalid response from the upstream server.

530 - Site is frozen (Unofficial Code)

Libraries vs Frameworks A  library  is essentially a set of functions that is called by the code, which are organized into classes. Each call to a library does some specified set of operations. A  framework  possesses some high-level design, with more built-in functions and behaviors. In order to use it you need to insert your own behavior into various places in the framework either by subclassing or by plugging in your own classes. The framework's code then calls your code at these points. Ok now, JS! Every day a new  JavaScript library is born! A few years ago, JavaScript (hereafter referred to as JS) was used for web-based front end development. Now, it is not only a front-end development platform, instead, it has numerous dimensions such as back-end development, database language, IoT capable language etc. etc. In addition, like all the other programming languages, frameworks are very common and popular in JS. But, in addition to that, n...

What is Node.js? Node.js is a free and open source server environment. That is, Node.js brings JavaScript to the server and guess what it is platform independent. Node.js lets developers use JavaScript to write command line tools and for server-side scripting to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere"  unifying web application development around a single programming language, rather than different languages for server and client. Node.js was implemented by Rian Dahl in 2009 and combines the following, Google Chrome's V8 engine An event loop Package management (npm) Chrome V8 Engine This compiles JavaScript directly to native machine code before executing it, instead of more traditional techniques such as interpreting bytecode or compiling the whole program to machine code and executing it from a filesystem. The compiled code is additionally optimized...
