ASP.NET in a Nutshell

Name

IsSecureConnection

Synopsis

boolvar = Request.IsSecureConnection

Returns a Boolean indicating whether the current connection uses secure sockets (SSL) for communication.

Parameters

boolvar

A Boolean variable to receive the SSL status of the current request.

Example

The example shows how you can take different actions depending on whether or not the current request was made via SSL:

Sub Page_Load(  )
   Dim boolvar As Boolean
   boolvar = Request.IsSecureConnection
   If boolvar = True Then
      Message.Text = "Connection is HTTPS."
   Else
      Message.Text = "Connection is HTTP."
   End If
End Sub

Notes

You would typically use this property to determine whether or not to fulfill a request that requires an SSL connection in order to encrypt sensitive data (such as credit card numbers) that might be submitted via the requested page. Additionally, you could use this property on a page that may or may not use SSL to determine how to render output to the page depending on the SSL status. Since encrypting and decrypting content for SSL communication exacts a performance penalty, reducing the number and/or size of graphics used on SSL-enabled pages is generally considered good practice. With this property, you could render more and/or higher-resolution graphics when SSL is not enabled for the request, and render fewer and/or lower-resolution graphics for SSL requests.
