I'm not a programmer, so I hope I can explain this problem well enough. I have a site that (for sales purposes) needs to have a registration w/ a username and password. All pages on the "inside" (post-login) are dynamic and all on the "outside" (pre-login) are static. We are moving an increasing amount of information to the outside for access by the press etc, but that results in creating new pages (thus making our site even larger!).

I think my question would be:
Is there a way to retain the login information (it contains an important ID), while the user moves "inside" and "outside"?

If this is confusing (and I'm sure it is), please contact me for clarification. Thanks!
