How to get the root url of the current site

16 Jan 2007

I have situations where I need the domain name and the application path of the current page (request ).

if the current request was http://www.myserver.com/website1/page.aspx

I need http://www.myserver.com/website1. Though the web.config can store this setting, I don’t want to change the config each time I move the site between servers.

So here is a little function I wrote.

Request.Url.AbsoluteUri   gives http://www.myserver.com/website1/page.aspx

Request.ApplicationPath gives /website1/. Subtract page.aspx from http://www.myserver.com/website1/page.aspx

 

public static string GetSiteUrl() {

if (HttpContext.Current.Request.ApplicationPath == “/”) {
     return “/”
}

          string url = HttpContext.Current.Request.Url.AbsoluteUri;
            int end = url.IndexOf(HttpContext.Current.Request.ApplicationPath) +
                  HttpContext.Current.Request.ApplicationPath.Length;
            url = url.Substring(, end);
            return url;
        }
