HTTP - Common Method Properties
Each method implements a different semantics
1.Safe
2.Idempotent
3.Cacheable
Cacheable Methods - Request methods can be defined as cacheable to indicate that responses to them are allowed to be stored for future reuse
There are specific headers in the response, like Cache-Control, that prevent caching
However, a response to a POST request can also be cached if freshness is indicated and the Content-Location header is set
Methods like PUT or DELETE are not cacheable, and their result cannot be cached
cacheable methods: GET, HEAD (sometimes POST)
non-cacheable methods: POST, PUT, DELETE, CONNECT, OPTIONS, TRACE, PATCH
