vaadin8 - Preventing Clickjacking attack by Vaadin -


i want prevent clickjacking attack in vaadin 7 , 8 apps. vaadin applications default designed embeddable, configuration or code needed add safety.

here's first experiment, adds x-frame-options header each response force browser use same origin policy.

public class myvaadinservlet extends vaadinservlet {    @override   protected void service(httpservletrequest request,       httpservletresponse response) throws servletexception, ioexception {          // add clickjacking prevention         response.addheader("x-frame-options", "sameorigin");          super.service(request, response);   }  }

i'd know if there better solutions vaadin apps, existing vaadin configuration options don't know or if implementation has drawbacks or limitations.

we have apache in front of our application, don't know if brittle add header manipulation there instead of having inside app (where can tested , changed developers).

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
