+
+HTTP(S) POST/GET request
+------------------------
+Performs a HTTP(S) POST/GET request and returns the HTTP status code and the reply data.
+If an error occurs then the error code and the message will be returned.
+Optionally, the result can be written to a file on disk.
+By default the algorithm will warn on errors. Optionally, the algorithm can be set to treat HTTP errors as failures.
