@@ -285,8 +384,40 @@ your Bugzilla installation. For example, if your Bugzilla is at
C<bugzilla.yourdomain.com>, then your JSON-RPC client would access the
API via: C<http://bugzilla.yourdomain.com/jsonrpc.cgi>
-Bugzilla only allows JSON-RPC requests over C<POST>. C<GET> requests
-(or any other type of request, such as C<HEAD>) will be denied.
+=head2 Connecting via GET
+
+The most powerful way to access the JSON-RPC interface is by HTTP POST.
+However, for convenience, you can also access certain methods by using GET
+(a normal webpage load). Methods that modify the database or cause some
+action to happen in Bugzilla cannot be called over GET. Only methods that
+simply return data can be used over GET.
+
+For security reasons, when you connect over GET, cookie authentication
+is not accepted. If you want to authenticate using GET, you have to
+use the C<Bugzilla_login> and C<Bugzilla_password> method described at
+L<Bugzilla::WebService/LOGGING IN>.
+
+To connect over GET, simply send the values that you'd normally send for
+each JSON-RPC argument as URL parameters, with the C<params> item being
+a JSON string.
+
+The simplest example is a call to C<Bugzilla.time>:
+
+ jsonrpc.cgi?method=Bugzilla.time
+
+Here's a call to C<User.get>, with several parameters:
+
+ jsonrpc.cgi?method=User.get&params=[ { "ids": [1,2], "names": ["user@domain.com"] } ]
+
+Although in reality you would url-encode the C<params> argument, so it would
+look more like this:
+
+ jsonrpc.cgi?method=User.get&params=%5B+%7B+%22ids%22%3A+%5B1%2C2%5D%2C+%22names%22%3A+%5B%22user%40domain.com%22%5D+%7D+%5D
+
+You can also specify C<version> as a URL parameter, if you want to specify
+what version of the JSON-RPC protocol you're using, and C<id> as a URL
+parameter if you want there to be a specific C<id> value in the returned
+JSON-RPC response.
