Page not found error occurs ....but the pages are alredy uploaded ...

eticket.aspx and website http://www.volvobusesindia.com

---

Check what controls the page is using, part of the error is:

(or one of its dependencies)

This means that if for example you're using MyControl.ascx and such file doesn't exist, you'll get the same 404 error.

---

Check if the page

 eticket.aspx

exists in the root folder of your application. A quick check online shows that eticket.aspx doesn't exist in the root of www.volvobusesindia.com.

Maybe your application is in a subfolder?

---

http://www.volvobusesindia.com/eticket.aspx gives me 404 page not found exception. Can you check again for the existence of this page?

---

Few points:

1. Is your current context is clixngo.com or volvobusesindia. If its volvo buses india, then we are encounter 404.

2. Response.Redirect(~/..) will only work on current domain. for other domain you have to specify the whole string.
