transferring from http to https session lost

Windows Server 2008 R2 v6.1 - IIS v7 - ASP Classic

On the http side I populate a cookie for zipcode. Then, for checkout, I do a Response.Redirect("https://www.mysite/getinfo.asp")

It works as expected in IE. But fails in Chrome and Firefox with the same basic error: too many redirects. Reason being it does not pick up the cookie zipcode. I saw this fix ASP > Services > New ID on Secure Connection: False in this forum, but it does not work.

Then I tried Server.Transfer("https://www.mysite/getinfo.asp")

That didn't work either. Any tips on what I'm missing?

Thanks!
