What's the purpose of the HTTP-methods GET, POST, PUT, DELETE, HEAD etc.

Is it just a convention to indicate, what I'm intending to do? Or is it, that certain HTTP-features are only available if I use a specific method?

GET requests:

• GET requests can be cached
• GET requests remain in the browser history
• GET requests can be bookmarked
• GET requests should never be used when dealing with sensitive data
• GET requests have length restrictions
• GET requests are only used to request data (not modify)

POST requests:

• POST requests are never cached

• POST requests do not remain in the browser history

• POST requests cannot be bookmarked

• POST requests have no restrictions on data length

now I hope you understood the difference between GET and POST. In similar ways, every method has different purpose.
