Difference between HTTP 1.0 and 1.1

HTTP 1.1 has a required Host header by spec. HTTP 1.0 does not officially require a Host header, but it doesn't hurt to add one, and many applications (proxies) expect to see the Host header regardless of the protocol version. ... Your web server can use the Host field to distinguish which site the client machine wants.

Is HTTP 1.0 still used?

Short answer: Yes. Long answer: You can't say that HTTP 1.0 is extinct. Basically there are a lot of tools that are coded using 1.0 so if you are working on a proxy you have to support both 1.0 and 1.1.

What is the meaning of 1.1 behind HTTP?

HTTP 1.1 provides faster delivery of Web pages than the original HTTP and reduces Web traffic. ... Instead of opening and closing a connection for each application request, HTTP 1.1 provides a persistent connection that allows multiple requests to be batched or pipelined to an output buffer .
