HTTP means Hyper Text Transfer Protocol.HTTP 1.1 generally an upgrade of limitations of HTTP 1.0.

The main difference between them is:
HTTP 1.0 can define 16 status codes
HTTP 1.1 can define 24 status codes
HTTP 1.0 authentication unsafe as it is not encrypted
HTTP 1.1 safe as it uses a check-sum of username, password and one time value and uses encryption.

Hi!

Here's some differences between HTTP 1.0 and HTTP 1.1.

HTTP 1.1 has a required Host header by spec.
HTTP 1.0 does not officially require a Host header.

HTTP 1.1 can have more than one request/response on the same HTTP connection.
HTTP 1.0 you need to open a new connection for each request/response pair.

HTTP 1.0 can define 16 status codes while HTTP 1.1 can define 24 status codes.

HTTP 1.0 authentication is unsafe while HTTP 1.1 is safe as it uses username and password.

Hope it helps!!

HTTP 1.1 additionally permits you to have persevering associations which implies that you can have more than one solicitation/reaction on the same HTTP association.

In HTTP 1.0 you needed to open another association for every solicitation/reaction pair. Also, after every reaction the association would be shut. This lead to some enormous productivity issues as a result of TCP Slow Start.

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 expect to see the Host header regardless of the protocol version.
