If you set the:
'X-If-No-Redirect' header to true or 1,
the the calendar server will respond with a 412 error code instead of a 302, and have the
'X-Redirect-Location' header in the response. That header would be the URL you want to access.
Try that.

Hi,
Thanks very much Frank, that answer makes good sense to me and I'm
slightly reassured. It also explains somewhat why I didn't have to
perform the 3rd step towards adding an event described on the calendar
api page - involving the session token.
I am indeed relying on wininet (/the internet transfer control) so
that is very plausible. The only downside is that as you say the
redirect happens automatically, so my application never gets to see
the 302; but rather the resulting 401.
I guess there's no especially simple way of dealing with this properly
with the tools I'm using? I'm not writing anything massively important
so I suppose I could just check for the 401 and if it happens, repeat
the request :-). If it gives 401 several times there is obviously
something wrong so it should quit and report the error.
Thanks!
