Question
Problem with Duplicate QueryString Values when redirecting for login. Help!
Not sure how this happened, but I have a number of .Net applications that all point to one central application for Authentication.
Recently, everytime those applications redirect they put thier quesrystring values on the url twice, like this:
http://mydevsite/login?Ret
I can't figure out how or why this is happening, and I cant figure out how to debug this.
What I do know is this:
When i try to access a protected resource, such as http://mydevsite/myapp/def
By the time I hit http://mydevsite/login/ 's code behind's page load, the querystring values have already been duplicated.

I have a Is PostBack check on both the page that is redirecting, and the login page that it is going to.
deighton:
Using forms based authentication. Yes, the fact that I am not signed on is the reason I am being redirected to the login page. That part is working correctly. the problem is that either that application is passing a returnUrl that has duplicate queryString parameters, -OR- the login applicatin is somhow mangling the returnUrl so that the querystring values are duplicate.
What I do know is that when I place a breakpoint in the login application's pageload and inspect the HttpContext.Current.Reques

Make sure that in PAGE LOAD you got IsPostBack check when appending querystring while redirecting.
I guess when page is been postback it is appending backed the code is not checking IsPostBack property.
