Using HTTPS protocol

[Sobha Pamarthi]

Hi,
I configured Tomcat 4.1 to work with HTTPS protocol. And am using URL encoding(Query String) to pass parameters to
subsequent screens. But I don't want the User to understand what parameters am passing to the next screen. Please help
me how to achieve this. Heard that HTTPS will encrypt and decrypt the Query String. We are using J2SDK 1.4.1_04.

Presently am sending secure information thru session. How this impacts the overall peformance? Will it be more fast
and efficient with regard to performance if I use query string to pass the parameters or setting them to session.

Thanxs & Regards
SP
