How do I get the complete virtual path of an ASP.NET application

The domain name part of the path is not really a property of the application itself, but depends on the requesting URL. You might be able to reach a single Web site from many different host names. To get the domain name associated with the current request, along with the virtual path of the current application, you could do:

Request.Url.GetLeftPart(UriPartial.Authority) + Request.ApplicationPath

Technically, an "application" is a virtual directory defined in IIS and Request.ApplicationPath returns exactly that. If you want to get the folder in which the current request is handled, you can do this:

VirtualPathUtility.GetDirectory(Request.Path)

ASP.NET has no idea how to distinguish your sub-application from a bigger application if it's not defined as a virtual directory in IIS. Without registering in IIS, it just sees the whole thing as a single app.


The below code will solve the purpose, however you have to do a bit tuning for two types of scenarios:

  1. Hosted as separate web application.
  2. Hosted as Virtual application within a web application.

    HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + HttpRuntime.AppDomainAppVirtualPath;


Request.Url

it contains several points that you might consider to use, see the image below:
