Question

Is there any way to determine the url on which a website is being hosted from the Global.asax’s Application_Start event?

I’m trying to store the url so that my application can generate dynamic links that are emailed from a background process.

If I try to directly access the HttpApplication.Request object in this method, I get a runtime error:

System.Web.HttpException: Request is not available in this context

I ended up putting my code in the Global.asax’s Application_BeginRequest event.

        string url = this.Context.Request.Url.AbsoluteUri.Replace(this.Context.Request.Url.PathAndQuery, string.Empty) + this.Context.Request.ApplicationPath;
        if (url[url.Length-1] != '/')
        {
            url = url + '/';
        }
