I am dealing with a strange issue. Our code has a login process that, if the login is successful, forces to redirect the user to a home page.

That logic works fine locally, on the test server, on the dev servers, and in production. However, just in one environment that process doesn't work. It is throwing the following exception

Thread was being aborted. at System.Threading.Thread.AbortInternal() at System.Threading.Thread.Abort(Object stateInfo) at System.Web.HttpResponse.AbortCurrentThread() at System.Web.HttpResponse.End() at System.Web.HttpResponse.Redirect(String url, Boolean endResponse, Boolean permanent) at System.Web.HttpResponse.Redirect(String url) at DRMS.login.Page_Load(Object sender, EventArgs e) in login.aspx.cs:line 116

That is extremely strange as the line 116 points just to a bracket. Can somebody please help me with code? Thank you all in advance


At this point I am at a loss and run out of ideas, especially considering the very same code with the same configurations works in other regions/boxes, such as prod region, test region, or dev region

Down below I paste an entire code with attached lines

Thank you in advance for your all the help

I did already post this question in the StackOverflow and Forums.asp.net and it was suggested to:
Use Context.ApplicationInstance.CompleteRequest(); after the Response.redirect - didn't work
Use Server.Execute or use Server.Transfer instead of the Response.recirect. That allowed to get to view Public.aspx page (page that is being redirected to after the successfull login) but the authentication itself didn't happen. Thus, any other link wouldn't redirect to its corresponding page but would instead bring the user back to Login.aspx with the correcponding ReturnURL query string parameter.
I tried to use ThreadAbortException with (and without) Thread.ResetAbort() inside - didn't work

You said: it's a "different environment" (problem).

So, find the difference and / or make it the same. Sometimes the cause of death is unknown.

Solution 1

It may surprise you.. but this is exactly what is happening; as the redirect leaves the current code block before it is completed.
And I see you have already tried playing around with HttpContext.Current.ApplicationInstance.CompleteRequest(); to get around this; bet you tried changing the false to true on the Redirect method's overload.

I basically gave up on fixing all of these; and instead, implemented multiple layers of catch statements- effectively ignoring the Thread Abort
try {
  // code 
}
catch (ThreadAbortException) {
  // IGNORE: this is normal behavior for Redirect method
}
catch (Exception ex) {
  // error logging routine
}
As I am now working with MVC based sites, I am wrapping the Redirect within an extension to the standard View object and don't worry about the WebForm stuff anymore

just a note, having the line numbers included in your code makes it a real pain in the butt for others to read the code online or work with in an editor

Solution 2

Our team was able to find a solution

The error itself was very deceptive and irrelevant. The problem lied in the Authentication settings in the IIS

Went to our website, chose Features View -> Authentication -> Forms Authentication

Make sure that 'Requires SSL' is unchecked

An extremely bad idea. Your authentication ticket will now be sent with insecure HTTP requests, which means it could be stolen by anyone who can spy on traffic between your computer and the server.

Your site should only ever be accessed over HTTPS, and all cookies should be set to "secure" to ensure they're never sent over an insecure connection.
