+
+	method_head: STRING = "HEAD"
+			-- Asks for the response identical to the one that would correspond
+			-- to a GET request, but without the response body.
+			-- This is useful for retrieving meta-information written in response headers,
+			-- without having to transport the entire content.
+
+	method_get: STRING = "GET"
+			-- Requests a representation of the specified resource.
+			-- Requests using GET (and a few other HTTP methods)
+			--  "SHOULD NOT have the significance of taking an action other than retrieval"
+			-- The W3C has published guidance principles on this distinction, saying,
+			-- "Web application design should be informed by the above principles,
+			--  but also by the relevant limitations."
+
+	method_trace: STRING = "TRACE"
+			-- Echoes back the received request, so that a client can see what
+			-- (if any) changes or additions have been made by intermediate servers.
+
+	method_options: STRING = "OPTIONS"
+			-- Returns the HTTP methods that the server supports for specified URL.
+			-- This can be used to check the functionality of a web server by requesting '*'
+			-- instead of a specific resource.
+
+feature -- Methods intented for actions
+
+	method_post: STRING = "POST"
+			-- Submits data to be processed (e.g., from an HTML form) to the identified resource.
+			-- The data is included in the body of the request.
+			-- This may result in the creation of a new resource or the updates of existing
+			-- resources or both.	
+
+	method_put: STRING = "PUT"
+			-- Uploads a representation of the specified resource.
+
+	method_delete: STRING = "DELETE"
+			-- Deletes the specified resource.
+
+feature -- Other Methods
+
+	method_connect: STRING = "CONNECT"
+			-- Converts the request connection to a transparent TCP/IP tunnel,
+			-- usually to facilitate SSL-encrypted communication (HTTPS) through
+			-- an unencrypted HTTP proxy.
+
+	method_patch: STRING = "PATCH"
+			-- Is used to apply partial modifications to a resource
