Everything need to know about HTTP

what is HTTP and why need it

HTTP means HyperText Transfer Protocol. It is the underlying protocol used by the World Wide
Web that defines how messages are formatted and transmitted.

HTTP is a stateless protocol. This means that the server does not require to maintain information
or status about every user for the duration of multiple requests. This also means that the server
does not need to maintain a continuous connection with the client.

In a stateless protocol, the server opens a connection for every request and closes it after the
response is sent.
**Steps in HTTP requests processing
**

Client requests a connection with the server.
The server opens a connection with the client
The client makes a request to the server
The server processes the request
The server sends a response to the client
The client closes the connection.

HTTP Requests

The HTTP request method is used to indicate the action to be performed on the data
transmitted to the server. These are the types of request that you can make using HTTP

GET - requests for a data
HEAD - requests for data but without the response body
POST - submits data causing a change in state on the server
PUT - replaces the specified data with request data
DELETE - deletes the specified data
CONNECT - establishes a tunnel to the server
OPTIONS - describes the communication options for the target data
TRACE - perform message loop-back test along the path to the target data
PATCH - apply partial changes to data

Response Codes

The response codes also called status codes are a 3 digit integer to identify what has
happened to the request sent to the server. Responses are grouped in 5 classes which
are identified by the first digit of the code

1xx (Informational Resources) - the request has been received and the process is
continuing
2xx (Successful Responses) - the request was successfully received, understood, and
accepted
3xx (Redirection Messages) - further action must be taken in order to complete the
request
4xx (Client Error Responses) - request contains incorrect syntax or cannot be
fulfilled
5xx (Server Error Responses) - server failed to fulfill an apparently valid request

Everything You Need to Know about Apache Storm

The ever-increasing growth in the production and analytics of Big Data keeps presenting new challenges, and the data scientists and programmers gracefully take it in their stride – by constantly improving the applications developed by them. One such problem was that of real-time streaming. Real-time data holds extremely high value for businesses, but it has a time-window after which it loses its value – an expiry date, if you will. If the value of this real-time data is not realised within the window, no usable information can be extracted from it. This real-time data comes in quickly and continuously, therefore the term “Streaming”.

Analytics of this real-time data can help you stay updated on what’s happening right now, such as the number of people reading your blog post, or the number of people visiting your Facebook page. Although it might sound like just a “nice-to-have” feature, in practice, It is essential. Imagine you’re a part of an Ad Agency performing real-time analytics on your ad-campaigns – that the client paid heavily for. Real-time analytics can keep you posted on how is your Ad performing in the market, how the users are responding to it, and other things of that nature. Quite an essential tool if you think of it this way, right?

Looking at the value that real-time data holds, organisations started coming up with various real-time data analytics tools. In this article, we’ll be talking about one of those – Apache Storm. We’ll look at what it is, the architecture of a typical storm application, it’s core components (also known as abstractions), and its real life-use cases.

Let’s go!

Everything you need to know about HTTP Caching

Web Cache or HTTP Cache allows you to store a copy of a resource and serve it back when requested. Serving the item from the cache, instead of re-downloading it from the origin server eases the load on the server, improves performance, and reduces the bandwidth usage on the server. In this lesson, we look at the different types of caches, we look at the different HTTP cache headers such as expires, pragma, and cache-control. Also, we understand how the cache validation works and what are the different caching strategies.
