property TrustStorageCertificates: boolean; default False;
Determines whether certificates in the client storage will be used to verify the server certificate.
When verifying a certificate, the signature is checked in the entire certificate chain, up to the self-signed certificate. If a non-standard certificate, trusted by the client, was used to sign the certificate, that certificate can be added to the client storage.
Set TrustStorageCertificates to True to use the certificates kept in the client storage, in addition to the system certificates, when verifying the server certificate.
Set TrustStorageCertificates to False to use only the system ROOT certificates when verifying the server certificate.
The default value is False.
