How does it work?<\/p>\n
The first thing to understand, – it’s REALLY EASY<\/p>\n
I use an analogy of posting a letter<\/p>\n
You write the senders and receivers address on the envelope with the message inside<\/p>\n
The post is delivered as per the address<\/p>\n
Once received the envelope is opened and message received<\/p>\n
HTTP requests (in fact all communication) works the same way<\/p>\n
The message is wrapped in an ‘envelope’ with addresses<\/p>\n
On receiving, the addresses are removed and message is delivered<\/p>\n
More on that process and HTTP messages construction here:<\/p>\n
