A subtle "winhttp.dll error 12002 (The operation timed out)" error

The error was reported by a user.

Situation:
- Both the client and server are on the same machine, they communicate via HTTP. So the network is OK.
- Aside from this error, The TSQLHttpClient is working correctly - it's not that it could not connect to the server at all - it can.

Stack trace:

thread $afc (TOmniThread), inner exception level 1:
>> Exception, LastErrorMessage: {"EWinHTTP":"winhttp.dll error 12002 (The operation timed out)"}

I guess the server side did have a long process, too long for the client to respond.
