=== Page request ===
The browser(with SKATER at least) does the following with [[HTTP_Services|HTTPC]] for requesting the above page:
* Initializes the HTTP context and uses [[HTTPC:InitializeConnectionSession]] + [[HTTPC:SetProxyDefault]].
* Uses [[HTTP_Services|HTTPC]] command 0x250080 twice with cmd[1]=contexthandle: first time cmd[2]=0x3, second time cmd[2]=0x6.
* Then [[HTTPC:AddTrustedRootCA]] is used 48 times to setup 48 trusted root CAs.
* Then [[HTTPC:BeginRequest]] is used.
* Then [[HTTPC:ReceiveDataTimeout]] is used, the recv-size seems to be fixed to 0x20.
* Then [[HTTPC:GetResponseStatusCodeTimeout]] is used.
* Then [[HTTPC:GetDownloadSizeState]] is used.
* Then the HTTP context is closed.
