Is there a way that I can know what parameters are been implemented in the query string of one certain URL? For example, with the http://esri.com/rest/services/myself/?f=JSON, how can I know it can have this f=json parameter in the query string if I only have http://esri.com/rest/services/myself/ URL?
Thanks for your help!

The only way you could know is if the site owner tells you.
If you’re working with a REST API, its documentation should include this information. If you’re just going after some URL on the Internet, there’s probably no way for you to know.
