Final answer:
The primary differences between HTTP 1.0 and HTTP 1.1 include persistent connections, pipelining, chunked transfers, the mandatory Host header in HTTP 1.1, and advanced caching mechanisms.
Step-by-step explanation:
Difference Between HTTP 1.0 and HTTP 1.1
The Hypertext Transfer Protocol (HTTP) is a protocol used for data communication on the World Wide Web. The primary differences between HTTP 1.0 and HTTP 1.1 are in their performance optimization and functionality. HTTP 1.1 was introduced to overcome the limitations found in HTTP 1.0.
- Persistent Connections: HTTP 1.0 opens a new TCP connection to the server for each HTTP request/response pair. In contrast, HTTP 1.1 introduced persistent connections, allowing multiple requests and responses to be sent over a single TCP connection, reducing latency and improving loading times.
- Pipelining: HTTP 1.1 supports a feature called pipelining, which lets a client send multiple requests without waiting for each response, enhancing the communication efficiency.
- Chunked Transfers: HTTP 1.1 can send data in chunks with 'Transfer-Encoding: chunked' header, providing more flexible data transfer, whereas HTTP 1.0 doesn't support chunked transfer encoding.
- Host header: In HTTP 1.1, the 'Host' header is mandatory, supporting the use of virtual hosting, whereas, in HTTP 1.0, this header is optional.
- Cache Control: HTTP 1.1 has more advanced caching mechanisms, which include more cache control options for better handling of cached content.
