--ssl-allow-beast

This option tells curl to not work around a security flaw in the SSL3 and TLS1.0 protocols known as BEAST. If this option is not used, the SSL layer may use workarounds known to cause interoperability problems with some older SSL implementations.

WARNING: this option loosens the SSL security, and by using this flag you ask for exactly that.
