checking for enabled cookies?

[Jeff]

I have a vb.net application (2005) requiring session variables and want to
test to make certain that the user's cookies are enabled.

I can set a test session variable on one page and attempt to read it on the
next with the code below in order to determine if the user has their
browser's cookies enabled, but is there a good way to do this on the
first/default page without a redirect to another page that will actually do
the test?

Thanks
Jeff


'On first page
Session("CookiesEnabled") = True


'On second page
If Not AreCookiesEnabled() = True Then
Response.Redirect("~\CookieError.aspx")
End If

Public Function AreCookiesEnabled() As Boolean
On Error GoTo A
If Session("CookiesEnabled") = True Then
Return True
End If
A: Return False
End Function

Hello Jeff,

Your way is already the regular way we check if a client supports cookies.
This is also discussed in this article:

Basics of Cookies in ASP.NET
http://msdn2.microsoft.com/en-us/library/aa289495(VS.71).aspx

You may check the section of "Checking Whether a Browser Accepts Cookies",
it uses a similiar way. Also there is a lot about cookies in this article,
hope this help.

Sincerely,

Luke Zhang

Well i would modify the code to this

'On first page
Session("CookiesEnabled") = True


'On second page
If Not AreCookiesEnabled() Then
Response.Redirect("~\CookieError.aspx")
End If

Public Function AreCookiesEnabled() As Boolean
try
If cbool(Session("CookiesEnabled")) Then Return True
catch ex as exception
return false
end try
End Function

The code and flow of the pages in site above looks like what I'm looking for
my specific problem.

Thanks (and to Michel also)
