Data Transfer in Chunked Format in HTTP/1.1
Hello friends! Today we want to discuss an interesting feature of the HTTP/1.1 protocol known as "Data Transfer in Chunked Format". This feature allows us to send data in small chunks instead of sending all the data at once. This is particularly useful when the volume of data is large, making it very practical and efficient.
But why has this technique come into existence? It may be due to specific conditions where waiting for all the data to be available is not ideal. For example, we may be streaming a video or having a real-time report. By using Chunked Transfer Encoding, we can send data in multiple parts, and the user does not have to wait until all the data is received.
This method can operate as follows: each chunk of data starts with its own length and then the content, followed by a specific marker that indicates the end. This marker tells the server and the client that new data is starting, and similarly, when all data has been sent.
Next, we want to demonstrate a simple implementation of this feature using code. Join us to see how this is done!

Code Explanation
Now let's analyze this code line by line:
First Line:
HTTP/1.1 200 OKThis line indicates a successful status for the request and informs the client that everything has been processed properly.
Second Line:
Content-Type: text/htmlThis line specifies the type of content being sent, which here is HTML.
Third Line:
Transfer-Encoding: chunkedThis line indicates that the data is going to be sent in chunked format.
Fourth Line:
4This number indicates the size of the first chunk of data, which is 4 bytes.
Fifth Line:
WikiThis is the data of the first chunk.
Sixth Line:
5This number indicates the size of the second chunk, which is 5 bytes.
Seventh Line:
pediaThis is the data of the second chunk.
Eighth Line:
0This number indicates that there is no new chunk to send, and the transmission ends.
