Thank you all in advance for your opinions and suggestions.
Currently, I use a Web-Protect feature that was pre-installed as part of my hosting. Users select their name from a list, and then are prompted for their user id and password from a pop-up. If their user id and password are correct, they are directed to their corresponding directory and page then they download their "product" (PDF files). It is very important that those PDF files are only accessed by the user that has permissions to be in that directory.
I am looking for a type of user management script that will allow my users to log in from my index.html page (without a pop-up) then redirect them to their page. Most of the scripts and programs that I've found will do this, but will not direct the users to individual directories (or pages) based on their user ids. They want to direct them to "one-for-all" page. When Customer X logs in from my main page, I need them to be sent to /CustomerX/index.html, or even CustomerX.mysite.com/index.html. The main objective is to keep the '/CustomerX' directory secure, only Customer X can access the files in that directory.
I have seen a few ASP scripts that are similar to what I'm looking for, however my web hosting is not equipped to handle ASP, and I am not in a position to change hosting, so I have been looking for alternative methods. I would greatly appreciate any suggestions, comments or guidance.
