Options that can be set via the Options parameter to the cUrlClient calls:
-"MaxRedirects": The maximum number of allowed redirects before the client refuses a redirect with an error
+"MaxRedirects": The maximum number of allowed redirects before the client refuses a redirect with an error
+"OwnCert": The client certificate to use, if requested by the server. Any string that can be parsed by cX509Cert.
+"OwnPrivKey": The private key appropriate for OwnCert. Any string that can be parsed by cCryptoKey.
+"OwnPrivKeyPassword": The password for OwnPrivKey. If not present or empty, no password is assumed.
Behavior:
- If a redirect is received, and redirection is allowed, the redirection is reported via OnRedirecting() callback
