PreviousPage is null

[Bryce]

I have a search page that submits to a search results page. I have set
the search results page to be authenticated, so when the user first
tries to search, it redirects them to a login screen. When they log in,
it goes to the search result screen. But when I do, the PreviousPage
variable is null.

Once logged in, when I go from the search to the search results screen,
PreviousPage is fine.

I'm using the authentication built into dot net using the following in
my web.config file:

<configuration...
<system.web>
...
<authentication mode="Forms" />
...
</system.web>
<location path="SearchResults.aspx">
<system.web>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</location>
</configuration>

The login form uses the System.Web.UI.WebControls.Login control.

I'm assuming that this uses a redirect? And this is why I'm losing the
PreviousPage? Any way around this other than putting the search
information in a session variable?

I believe PreviousPage works if you use Server.Transfer, but not if you use
Response.Redirect.

Thanks. But do I have the option of controling which mechanism it uses
to transfer to the intended control using the
System.Web.UI.WebControls.Login control and the asp.net authentication?

Yes.
And you might also be able to use Request.URLReferrer depending on your
needs.
