how to use header Authentication to display mashup with iframe without login

[baharehkh]

Hi 

We have already created mashups from the qlik sense dashboards.i want integrate this mashup in html page.

we want  user open this html page without login page from qlik sense, and for this i used 
header Authentication and create a virtual proxy according to this topic:

Header authentication and Qlik Sense 

my Problem is how to use this virtual proxy in iframe  and pass header parameters and finally display mashup in iframe.

i used this code but still it did not display my mashup and i get error 401 and access is denied by qlik sense.

...ek is my virtual proxy name

how do i should use this virtual proxy in html page?

Please advice how to have authentication done at the backend without the user enter Qlik Sense credentials using iFrame  and Header Authentication proxy
