HTTP SSL Connection & Invalid Certificates

Hello

I have a problem connecting to webserver thru SSL protocol. I want to send
SOAP request using THTTPRIO component (but which component it is does not
matter I think). There are calls to HttpOpenRequest and HttpSendRequest from
wininet. I must to connect to webserver which have SSL certificate signed by
themselves not by the certified authority center (CA root certificate is not
trusted). So this certificate is bad. I have set option in THTTPRIO
soIgnoreInvalidCerts which puts flags INTERNET_FLAG_IGNORE_CERT_DATE_INVALID
and INTERNET_FLAG_IGNORE_CERT_CN_INVALID to HttpOpenRequest. Connection is
opened successfully, but when I want to send data using HttpSendRequest an
error occurs. Error says that there is not valid certificate.

What can I do?

Regards,
Arek
