Ans. 1. Clear session or application variable using remove method of session and application class like
Session["x"]="Value";
Session.Remove("X"); remove the value of x session

Ans 2. use the pageerror event of class and then use Session.GetLastError() method of session class and also get the address of page using object of http class to find the current request page url.

Ans 3. Yes it carry the session value.

Solution 2

hi,
ans 3.
if u have a session or any lines of code after response.redirect then it will not executed as page is being redirect. in case you want to execute that code you will have to write false flag of response.redirect.

response.redirect("somepage.aspx",fasle);
your code here...

by default it is true...so page will redirect and we have not habit to write true flag....

@kkakadiya- yes your right, session cannot be created if response.redirect comes first.
@kavithadev- I think instead of asking these basic que, you should do it programmatically and check the results, this will increase your programming basics
