The one such document that I would recommend you to read is [Key differences between `HTTP/1.0` and HTTP/1.1](http://www.ra.ethz.ch/cdstore/www8/data/2136/pdf/pd1.pdf) and here is the link to [original RFC](https://tools.ietf.org/html/rfc2616) for the overachievers. -`HTTP/1.1` was introduced in 1999 and it had been a standard for many years. Although, it improved alot over it's predecessor; with the web changing everyday, it started to show it's age. Loading a web page these days is more resource-intensive than it ever was. A simple webpage these days has to open more than 30 connections. Well `HTTP/1.1` has persistent connections, then why so many connections? you say! The reason is, in `HTTP/1.1` it can only have one outstanding connection at any moment of time. `HTTP/1.1` tried to fix this by introducing pipelining but it didn't completely address the issue because of the **head-of-line blocking** where a slow or heavy request may block the requests behind and once a request gets stuck in a pipeline, it will have to wait for the next requests to be fulfilled. To overcome these shortcomings of `HTTP/1.1`, the developers started implementing the workarounds, for example use of spritesheets, encoded images in CSS, single humungous CSS/Javascript files, [domain sharding](https://www.maxcdn.com/one/visual-glossary/domain-sharding-2/) etc. +`HTTP/1.1` was introduced in 1999 and it had been a standard for many years.
