Jean, Out of curiosity, why a Windows program? Building this kind of security using a web based system is not particularly difficult or unusual, but I'm not sure about doing this through a desktop application. If nothing else the link to referral URL would be more tenuous. Not that I know that much about software for that kind of connection other than the very basics, but it does seem to be a bit unusual. Web based interfaces for this kind of thing, using AJAX, Flash or even plain HTML are far more common and can be made to behave very much like a desktop application. unless this is something you need to interface with an existing application. -Dan -----Original Message----- From: hidden-discuss-bounces at lists.hidden-tech.net [mailto:hidden-discuss-bounces at lists.hidden-tech.net] On Behalf Of Jean Graef Sent: Wednesday, April 18, 2007 6:34 AM To: Hidden-discuss at lists.hidden-tech.net Subject: [Hidden-tech] Password-protection program? I am looking for a Windows program to provide password-protected access to content on our members site. The program should be able to: -- Use a list of user names and passwords to provide access to one or more Web site directories -- Provide access based on referral URL and/or the user's IP address -- Limit the number of concurrent user logins when accessing via referral URL or IP address Does anyone know of a program that will do this? I want to avoid using the built-in security features of Windows.
