How can I get around this by using a long string in the form callback return??

HTTP Error 404.15 - Not Found The request filtering module is configured to deny a request when the query string is too long.

Most likely causes: Request filtering is configured on the Web server to deny the request because the query string is too long.

Actions you can try: Check the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting in the applicationhost.config or web.config file.
