How to pass information between pages?

Out of many choices one choice is to make use of Query String property of Request object, which allows us to pass information between pages. For example to pass information: Response.Redirect(“Newpage.aspx?Name=”+txtName.Text +”&Age=”+txtAge.Text); To Retrieve information: String name=Request.QueryString[“Name”]; String age=Request.QueryString[“Age”]; Advantages: 1. It is easy to use and is light weight. DisAdvantages: 1. It has Max length of 1or 2 kb ,so limited information can be passed. 2. It is visible in address part of the browser and hence we cannot send any sensitive information. 3. QueryString cannot be used to send ‘ &’ and ‘space’ characters. To solve this problem we have to use Server.UrlEncode. For example above code can be rewritten as: Response.Redirect(“Newpage.aspx?Name=”+Server.UrlEncode(txtName.Text )+”&Age=”+Server.UrlEncode(txtAge.Text));
