Hi,

I have faced a problem with response.redirect.

There is a basic web application. The response.redirect works on local server. However, when I deployed the application on the main server, the response.redirect does not work and it just refreshes the page. The problem also exists for the Menu control. The menu navigation works on local machine but not on the main server. Could you please tell me how can I fix it.

Can you show me the code you are using to Redirect to another page?

It's a very basic code.

protected void btnLogIn_Click(object sender, EventArgs e)
{
    /*User objUserBusiness = new User();
     objUserBusiness.UserName = txtUser.Text;
     objUserBusiness.PassWord = txtPass.Text;
     if (objUserBusiness.UserLogIn(objUserBusiness))*/
          Response.Redirect("Default.aspx");
     /*else
          lblIdPass.Text = "Invalid Username or Password.";*/
     }

protected void btnNewUser_Click(object sender, EventArgs e)
{
      Response.Redirect("CreateUser.aspx");
}

The code looks good. Are you sure the target page is simply refreshing and not being redirected back to from either CreateUser.aspx or Default.aspx?

Do you have an code in your page load that would cause the request to be terminated?

After running response.redirect, The URL in address bar shows the address of the next page, but the page that is shown is the first page.

I have used some validation controls.

 I also need to mention that I used Server.Transfer, it worked but again in next page the Menu (standard asp menu control) does not work. I mean by selecting each item from menu, it is supposed to get redirected to a particular page. However, nothing happens.

I could find a solution by making a comment for authorization section of the web.config as follows:

1 <authentication mode="Forms">
2 <forms name=".ASPXUSERDEMO" loginUrl="login.aspx" protection="All"/>
3 </authentication>
4 <authorization >
5
6 </authorization>

It solved the problem and pages are redirected properly by response.redirect. Before I state the second problem, Could you please tell me whether it was an appropriate solution?.

Second Problem: I could send email based on the following code on local server.

MailMessage mailMSG = new MailMessage();
mailMSG.Body = "........";
mailMSG.To = "[email protected]";
mailMSG.Subject = "Your Login details";
try
  {
     SmtpMail.Send(mailMSG);
  }
  catch (Exception ex)
  {
     Response.Write("Failure in sending email:" + ex.ToString());
     return;
   }

However, this code fails on main server (works on local server) and gives me the following error

"Failure in sending email:System.Web.HttpException: At least one of the From or Sender fields is required, and neither was found. ---> System.Reflection.TargetInvocationException: Exception has been thrown

Could you please tell me why this error happens?

Whether or not it is appropriate depends largely on how your application is setup. I typically see the <deny users> code, as you have provided, inside of child web.config's in which a developer wants to restrict access to only users who have logged in.

Try adding a From value to correct your second error.

Thanks for your help, I added mailMSG.From, but the problem still exist. These errors are very strange. Do you think I need to talk to admin to re-install IIS on main server?
