Sending special characters in Querystring

When you need to pass some special charaters(+, % etc.) in Querystring you will need to encode it first before redirecting.

Response.Redirect(www.abc.com/createtask.aspx?taskID= + Server.UrlEncode(Session["TaskGUID"].ToString())

This is very helpful when you are going to send some GUID values.
But keep in mind don't use Server.UrlDecode in createTask.aspx page as Request.Querystring automatically recieves decoded string.
