RequireSSL set to true, some cookies not marked as secure

[Phil Johnson]

Hello,

I have an asp.net 3.5 website and need to ensure that all cookies are marked
as secure.

I set the following setting in the web.config file expecting all cookies to
be marked as secure but most are not. At a quick look it appears that only
the asp.net authentication cookie is marked as secure.

<httpCookies httpOnlyCookies="true" requireSSL="true" domain="" />

Does anybody know what I can do to make sure that all cookies are marked as
Secure? Ideally by using configuration.

Thanks,

Phil
