Redirect a custom url with a webservice? Other options?

I have a home server running at home 开发者_开发技巧and I want to grant family members access to certain private websites.

Reese with password 1234 should type in his url like this: http://www.my.my/reese1234 and get redirected to where I want him to be redirected to.

Can I use a webservice for this? If yes, how do I start? (I use ASP.NET and C#) Or is there a better option which will also improve performance? Of course I want to redirect with the least amount of performance so other processes will be on max bandwidth.

A Web Service isn't your best option.

I would suggest creating a custom HttpHandler to do what you need. (Actually, I wouldn't suggest doing username/password authentication/redirection this way at all...but that's not the point of the question).

You do not need to write code, you can set your server up to do this for you. I assume you are using IIS, take a look at this: password protecting folders in IIS.
