I would like to block the access to my website while I make changes to it. But I want some selected people and myself to have access to do tests. I found this method which is good (http://25yearsofprogramming.com/blog/20070704.htm), except for the fact it is based on ip addresses (I don't know the ips of everyone and can't ask).
How can I do the following: - redirect all urls to a page like maintenance.php - on that page, there is a form that people can use to enter a code - if the code is valid, the redirection stops and they have access to the website normally
Thanks
If you dont want to use ip addresses you can setup htaccess with passwords for the your testers and everybody else will be redirected.
