The Differences between HTTP/1.0 and HTTP/1.1:

1. 
   - HTTP 1.0 supports nonpersistent connection.
   - HTTP 1.0 used a different TCP connection for each request.This includes files embedded in a web page. Consider a web page with four embedded .jpg images. A separate TCP connection must be established for each image file in addition to the web page itself.

2. 
   - HTTP 1.0 defined a limited number of response codes (sixteen codes). Finer-grained error reporting requires a larger pool of response codes. 
   - The codes of HTTP 1.1 includes is more than second times of HTTP 1.0 includes.

3.
   - HTTP/1.0 requests do not pass the hostname part of the request URL.
   - HTTP/1.1 requires requests to include a Host header.

4.
   - HTTP 1.0 supports multiple Web sites from a single IP address, which may creat serious problems.
   - HTTP/1.1 accepts absolute URIs to adapt to the growth of the Web, and the developing number of servers.
