+/*!
+ \enum QSsl::SslOption
+
+ Describes the options that can be used to control the details of
+ SSL behaviour. These options are generally used to turn features off
+ to work around buggy servers.
+
+ \value SslOptionDisableEmptyFragments Disables the insertion of empty
+ fragments into the data when using block ciphers. When enabled, this
+ prevents some attacks (such as the BEAST attack), however it is
+ incompatible with some servers.
+ \value SslOptionDisableTickets Disables the SSL session ticket
+ extension. This can cause slower connection setup, however some servers
+ are not compatible with the extension.
+ \value SslOptionDisableCompression Disables the SSL compression
+ extension. When enabled, this allows the data being passed over SSL to
+ be compressed, however some servers are not compatible with this
+ extension.
+ \value SslOptionDisableServerNameIndication Disables the SSL server
+ name indication extension. When enabled, this tells the server the virtual
+ host being accessed allowing it to respond with the correct certificate.
+
+ By default, SslOptionDisableEmptyFragments is turned on since this causes
+ problems with a large number of servers, but the other options are disabled.
+
+ Note: Availability of above options depends on the version of the SSL
+ backend in use.
