I am passing a large amount of data in a query string. when I have about 3000 char. that are being passed the form on the next page will not let me submit. I'm thinking of using session variables to handle this but I'm not sure if there is a limit of Char. a session variable can handle. Also I'm worried about how bad this will slow down the server. the variable only has to be open for the next two pages then I can close the session variable. Has anyone come across this before? Any tips on how to do this differently?
