Final answer:
HTTP 1.0 differs from HTTP 1.1 mainly in persistent connections, caching mechanisms, and the host header, with the latter introducing improvements in each area.
Step-by-step explanation:
Differences Between HTTP 1.0 and 1.1-
The Hypertext Transfer Protocol (HTTP) is a protocol used for transmitting web pages over the internet. Two of its versions, HTTP 1.0 and HTTP 1.1, have some distinct differences. Firstly, HTTP 1.1 introduced the concept of persistent connections, allowing multiple requests and responses over the same TCP connection; meanwhile, HTTP 1.0 did not support this feature and required a new connection for each request and response.
Another difference lies in the caching mechanisms provided by HTTP 1.1, such as cache control headers, which are more enhanced compared to HTTP 1.0.
Additionally, HTTP 1.1 supports a host header, making it possible to host multiple domain names on a single IP address. This functionality is not present in HTTP 1.0.
