How Do I Make A Password Redirect To A Web Directory (Folder)?

What I need to know is very simple.

I use to know the script where I could create a form text box and depending on what a person typed in the text box, they were redirected to a different folder in my domain name's hosting account.

For example, if I gave one group of people the password: EBAY123, and they entered into the password text box, they would then be directed to mywebsite-net/EBAY123 and then of course they would automatically go to mywebsite-net/EBAY123/inex.html. If the passwords was BITCOIN234 they could be redirected mywebsite-net/BITCOIN234 to a web page that would offer to sell them secrets of Bitcoin mining. I could have unlimited offers available controlled by passwords given to different people so someone please refresh my memory on how to make this HTML script. Not interested in Java as you'd have to put the directory in the code and a savvy person would simply view the websites HTML to get in without a password. Thanks

 

I think you need PHP code for this.

 

Perhaps it was a PHP code I was using all those years ago. Can someone give me a PHP code then?

 

Hire a good developer discover best guidance or better if you are a developer then search code on the Google.

 

Seems not possible because you need to have a separate user name also along with separate password in order to that task.
