    For sites that use valid certificates, you shouldn’t have to do anything special, other than specifying the https URL, of course. For self-generated certificates you may need to manually install the certificate authority on the client machine, and/or provide some of the IGNORE flags.

    A great way to troubleshoot issues like this is to install a WININET callback. This lets you monitor the progress that WININET is making (or not) while communicating.

    There’s an example (that I haven’t personally used) of how to use it here:
