Which is better between static variable and Application variable?

[mycwcgr]

In my website http://www.hothelpdesk.com , I hope to set a global variable to store domain. so I can access the value in my code anywhere.

I think both Method A and Method B can do that!

In Method A, I use static variable HotHelpDesk.BLL.PublicPar.MyDomain, so I can access the value of HotHelpDesk.BLL.PublicPar.MyDomain in my code anywhere.

In Method B, I use Application["MyDomain"], so I can also access the value of Application["MyDomain"] in my code anywhere.

Could you tell me what different between static variable and Application variable?

Could you tell me which one is better?

Many thanks!



//--------------------------Global.asax------------------------------------------
void Application_Start(object sender, EventArgs e)
{
// Method A
HotHelpDesk.BLL.PublicPar.MyDomain = HotHelpDesk.BLL.Par.GetDomian();

// Method B
Application["MyDomain"] = HotHelpDesk.BLL.PublicClass.GetDomian();
}
//--------------------------Global.asax------------------------------------------




//--------------------------PublicPar.cs-----------------------------------------

using System;
using System.Data;
using System.Configuration;
using System.Web;

namespace HotHelpDesk.BLL
{
public class PublicPar
{
public PublicPar()
{
}

public static string MyDomain;

public static string GetDomian()
{
string Full = HttpContext.Current.Request.Url.ToString();
string ToBoot = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath;
ToBoot = ToBoot.Substring(2);
Full = Full.Substring(0, Full.LastIndexOf(ToBoot));

return Full;
}
}
}

Have you tried Method A? I don't think static variables work in ASP.NET, because HTTP is stateless, so a new object instance gets created on each request.
