Can a cookie be made in HTTPS, and used in HTTP if secure parameter of the cookie is set false? I have a website where I only require a single page to be in HTTPS, such as the login or maybe a special feature page.
I assume that the cookie will be (safe as it is transfered with SSL) although sent back as non-hashed when on a non-SSL page, is safe to assume so?
In short: yes.
Setting a cookie on an SSL secured response, but leaving out the
secureflag, will make the cookie behave no different than if it was transferred over a non-SSL connection.
