Okay please bear with me, I'm designing my first site (for myself) that cannot fit on a floppy. So I am still very much a newbie, so I need your collective wisdom about netiquette.

Okay consider this scenario:
- A user goes to a page (displaying unique generated information (PHP/MySQL)) and a cookie is set.
- Next time the person comes back to the website, if they have been here previously, they are automatically forwarded to the unique page.

Is this okay or appropriate. From then on, when they click "Home" (present on every page) they are automatically forwarded to this unique page.

Ideas and suggestions.

Also what is the apropriate maximum size of any one page? Currently pages are about 20k and graphics are about 25k is this okay?
