Hi,

For testing purposes, does anyone know how to disable validation of
certificate authority within WinInet? I'm trying to connect to my own
secure site (https) and HttpSendRequest() keeps returning an INVALID_CA
(12045) error. I can't seem to find an approprate flag to pass into
HttpOpenRequest() to ignore "invalid" CA's. InternetSetOption() does
not seem to be the answer either. Overriding the WinInet user interface
via IsDialogBoxHandled()appeared promising, but the function never gets
called in this particular case. Anyone have any suggestions on how to
do this?

Thanks.

Duane.
