Switching Between HTTP and HTTPS

[Kenneth Keeley]

Hi
I wish to have a web site that has most of the pages as normal HTTP pages
but has some areas that use HTTPS. I want to have it that if a user selects
a link to a HTTPS page that they go there an there Session Information is
kept. I also wish to have the pages switch automatically to HTTPS if a
visitor types the URL without the HTTPS. So my questions are:
1) How to redirect to a Secure Page without losing Session Info?
2) How to test if page is accessed by HTTPS, and if not switch to HTTPS
quickly?

I think something like this code is what I want but how do I do it.

<%
if not "HTTPS" then
response.redire ct(https://mysite.com/securepage.asp)
end if
%>

Thanks for the help.

So my questions are:

This is not possible. Sessions cannot be maintained across different
protocols. You'll have to store the info server-side in a database, for
example.
2) How to test if page is accessed by HTTPS, and if not switch to HTTPS quickly?

Here's an example:

You'd probably also want to grab the querystring, should it exist. Maybe do
it like this instead (illustrative example):

<%
Dim sRedirect, sDomain, sPath, sQString
If UCase(Request.S erverVariables( "HTTPS") = "OFF" Then
sDomain = Request.ServerV ariables("SERVE R_NAME")
sPath = Request.ServerV ariables("SCRIP T_NAME")
sQString = Request.Queryst ring
sRedirect = "https://" & sDomain & sPath
If Len(sQString) > 0 Then sRedirect = sRedirect & "?" & sQString
Response.Redire ct sRedirect
End If
%>
