Error in Asp.Net : "Redirect URI cannot contain newline characters"

While you send the error message as query string to an error page using response.redirect method in asp.net, you may come across the following error.
To get through, you should use URLEncode and URLDecode alone or with combination of HTMLEncode and HTMLDecode.

Eg:-
Response.Redirect(@"~/errorpage.aspx?.err=" + Server.UrlEncode(exception.Message) + "&.src=" + Server.UrlEncode(exception.Source));
