4.1.2 Submit a petition request to the petition URL
The client submits a petition request to the petition URL and waits for the server's response. The petition request is a plain HTTP/1.0 GET request, as shown by this example:
-
GET PetitionPath HTTP/1.0 User-Agent: Client-User-Agent
If the petition URL contains "https", the client can use SSL for the connection. (For non-SSL transport, remove the "s" in "https" from the URL.) If SSL is used, the client could check the server's certificate to ensure it is current, matches the domain, and is properly signed by a trusted authority.
