I realize I can get to it in my redirect event, the problem is how do I pass that to the Login Widget? My case looks like this to start:
var url = unauthorizedEvent.Page.Url.TrimStart(
//for this specific page redirect to CustomerLoginPage
//for all other pages redirect to the Sitefinity login page
//if you do not use the else clause you will be redirected to the Sitefinity login page in all other cases different that the above one
Then how do I pass that to the line 16 Login redirect so that the standard login widget will accept the URL parameter or Post Parameter for that matter? I've tried passing it several different ways and none are picked up by the login to go to the page they were coming from.
