Persisting viewstate information between HTTP/HTTPS?

[Chris Ashley]

Is it possible to persist viewstate information between HTTP and HTTPS
(on the same page obviously)? Trying to get around writing some messy
state transfer code... it doesn't seem to work if I use
response.redirect.

What about using Server.Transfer which has the ability to preserve the
context of the pevious page ? Or have I misunderstood you ??

Sorry, I don't think I explained myself well enough.

Basically I have a webform which is wizard style with a number of
'pages'. The last step needs to use HTTPS but submit to the same form.
I know I can do this using client side script to override the form
action but that's not ideal.

EG:

switch (wizardStep)
{
case 1:
// Needs to be http
infoPanel.Visible = true;
break;
case 2:
// Needs to be http
declarationPanel.Visible = true;
case 3:
// Needs to be https
paymentPanel.Visible = true;
}

I know I can do this by just making a separate form, or adding some
code to pass values across, but just wondered if there was a neater way
that I'm missing?

Thanks,

Chris

Why not use HTTPS for all the stages, will this not work ?

If you need to use absolute URLs, resort to a little trick and manually add
the session ID to the URL. You use the ApplyAppPathModifier method on the
HttpResponse class.

<a runat="server"
href=<% =Response.ApplyAppPathModifier("/code/page.aspx")%> >Click</a>
The ApplyAppPathModifier method takes a string representing a URL and
returns an absolute URL, which embeds session information. For example, this
trick is especially useful in situations in which you need to redirect from
a HTTP page to an HTTPS page.
