Selling access to web pages on server

Within Zen Cart are you able to sell access to not downloadable documents but access to web pages with information on them. Scenario would be info is in secure directory and when people pay they are able to access the web pages. This would entail being able to give user names and passwords access to a directory. (User management).

PHP

I have searched the FAQ and am reading the manual.

I am very new at the PHP and store stuff. I have finally figured out and been able to customize the store. However I am having some isues on the product side. This is my scenario.

5 basic products which are actually web pages which will be protected. want people to buy them then have access to that area not download them. I was looking at user management systems but am I missing somethign basic here?

Thanks,
