Changing Properties from a Win Application to a Web Applicationg?

Question

Hi,

I have been trying to find ways around this code or to do something about it but I still don't understand a few things about creating websites in ASP.NET. So my problem is the following:

return int.Parse(Properties.Settings.Default["SiteId"].ToString());

and 

Main 

                Properties.Settings.Default["SiteId"] = value;

Any help translating from Win to Web will be really helpful.
