do you mean what they are as methods to HTTP::Request or what they are in general?

get - just gets a document
head - is generally just used to see if a document is present
post - sends data to the server
put - I don't think there is a put for HTTP::Request but I'm not sure

as far as in general:

http request methods

I think you are talking about a restful API.

GET : get a user
Head : checks a user exists
POST: Used to create a new user
PUT: Updade a users information

This is pretty much how restful API's I have worked on are.

Get : retrieve information
Post: create new entity and update existing entity
Put: create new entity and update existing entity but put request is idempotent
Head: obtaining metainformation about the entity
