The request method is usually either "GET" or "POST".
Basically if you fill in and submit a form on a web page it might
generate a POST request (or it might be "GET"), whereas if you just
click on a link, or activate one of your browser's "bookmarks" or
"favourites", then the request method will always be "GET".
Therefore, if it's "POST", we can tell that a form was definitely
submitted.
The contents of the form would appear here, and there would also be
some "Content-" headers describing the data.
Web browsers generate two kinds of "POST" data: either
"multipart/form-data", which is used when uploading files to a web
server, or the more common "application/x-www-form-urlencoded".
