cachePage and secureheaders

Hello all,

I would like to know if it is normal, when we use "$this->cachePage(xx);" in a controller, that the http headers of "secureheaders" are not present anymore?

http headers that disappear with the cache :

PHP Code:

x-content-type-options: nosniff
x-download-options: noopen
x-frame-options: SAMEORIGIN
x-permitted-cross-domain-policies: none
