Create an IFRAME Vkontakte application. Problem?

Question

Digital certificates

Is it possible to create a Vkontakte application without "Https" certification?
I do not consider the method of obtaining from startssl.com.

Answer 1

It is possible, but you will lose that part of VK visitors who go to https://vk.com/
Perhaps I'm wrong, but https:// can be raised without an SSL certificate.

Answer 2

now vk will forcefully redirect the user to https. So it is necessary to have a certificate. but it's not expensive or difficult. it is not necessary to purchase a certificate from Thawte. buy something cheaper.
