How do I "retain" webpage after logging in ASP.NET

C#

if (Session["username"] == null)
           {
               Response.Redirect("Signin.aspx");
           }

This is in webform3. This redirects me to my sign in page. After signing in I would like to go straight back to webform3 but my code then takes me to webform 2.

What I have tried:

Is there a spesific way to do it?
or should I save the url inside a session?

your code says signin but you're talking about webform3 and webform2, it's hard to understand what is going on. This could be a caching issue though, if you have redirected from a certain page and you go back to that page the browser might use the cached version which does the redirect. To see if that is what is happening add a random param to your redirects to get around cache issues

Response.Redirect("SomePage.aspx?r=" + DateTime.Now.Ticks.ToString());

Why are you re-inventing the wheel? ASP.NET has several perfectly good authentication systems built-in - for example, ASP.NET Identity[^]

Typically you would add a parameter to your URL - refer below;

C#

Response.Redirect("Signin.aspx?ReturnToPage=MyPagename");

Then after you have handled the authentication, you can redirect the user to the appropriate page using the following in your code-behind;

C#

Request.QueryString["ReturnToPage"];
