Prevent MIME type sniffing by disabling contentTypeOptions(). When the HTTP header X-Content-Type-Options is set to 'nosniff', an attacker will not be able to derive the data's file format by inspecting the byte stream.

Before
http.headers().contentTypeOptions();
After
http.headers().contentTypeOptions().disable();
