Only of the server-side logging intercepts will work. Just keep in mind,
though, that TIdTCPServer is multi-threaded, so make sure any logging you do
is thread-safe.

Accessing the GUI from the context of a worker thread is not thread-safe.

No.

Intercepts are triggered in the context of the thread that is accessing the
socket. You need to make sure that any code you put inside the logging
events are thread-safe. In this situation, you will have to use the TIdSync
or TIdNotify class to synchronize access with the GUI.
