ASP.NET Forms Authentication .NET 4 - Document Name missing from ReturnURL in the querystring

We have recently upgraded a web app from .Net 3.5 to .Net 4

This has introduced an issue with the ReturnURL in the querystring when logging in.

Prior to upgrade you could visit http://www.somedomain.com/myweb and on redirection to the login page the address would be this - http://www.somedomain.com/myweb/authenticate.aspx?ReturnUrl=%2fmyweb%2fdefault.aspx

Now after upgrade the address is as above but default.aspx is missing from the ReturnURL parameter.

After logging in you are redirected to a blank page.

The default document in IIS is set as before.

Does anybody have any idea whats causing the document name to be stripped from ReturnURL after upgrade?

sounds like the URL is built via code, and there's something missing in the build statement/the URL object used may have changed and you may now have to specify a property to copy the querystring with it... - MaxOvrdrv
Why is /myweb/ returning a blank page? What blank page is it displaying? - James Lawruk
Its not any specific page in the app. Looking at the source this is all thats there... <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD> <BODY></BODY></HTML> As far as i can see the issue is that default.aspx is missing from the ReturnURL param. It was all fine before the upgrade. - stu
MaxOvrdrv - i will look into that - stu
MaxOvrdrv I've had a search of the code and we dont build up the URL dynamically. I think this must be happening at the framework level as its only been an issue since changing .net version - stu

I've fixed the issue by placing the following code in Global.Application_BeginRequest

If HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath = "~/" Then HttpContext.Current.Response.Redirect("~/default.aspx") End If
