HELP NEEDED: HHTPS POST to Apache server fails

[RoffaBoffa]

No, as far as I have understood, no special build of Qt is required as long as the required DLL's are present in the applications' PATH at run time. If they are not, a call to QSslSocket::supportsSsl () will return FALSE. I use this method to verify that the PC supports SSL.

So (a) No, (b) Yes

I guess you're not quite right about SSL support.
IIRC Qt might be complied with or without OpenSSL support (and there might be two kinds of OpenSSL support(dynamic and static)).

Anyway I would suggest you to check whether your app loads OpenSSL dll's on runtime or not.

Thank's for the tip, llev, but alas, all my DLLs are being loaded at run time (ssleay32.dll, libeay32.dll, zlib1.dll)....

That's good.
Could you use some sniffer to log your app network traffic to determine whether it tries to issue such HHTPS request?
