​Request Methods

​HTTP uses an assortment of requests to indicate the desired outcome. The most popular request is the GET request. The other tasks that HTTP can perform are HEAD, POST, PUT, DELETE, CONNECT, OPTIONS, TRACE, and PATCH.

​Servers, which can be thousands of miles away, hold the code for HTTP. Larger files are broken down into smaller bits called packets.

HTTPS is active if you see a lock next to your browser address bar. The protocols that protect your browsing are called SSL (Secure Socket Layer) and TLS (Transport Layer Security).
