For a SharePoint hosted application, is the host web always referred to as a site collection, and it cannot be a web only ?

Let's assume I install a SharePoint hosted application at this address - which is a sub-sub web,

site collection - http://www.studentportal.com/sites/classroom2


So is site collection host web or sub-sub-web is host web...

  • what you mean by Host web? are you asking about the App perspective?

1 Answer 1


In regards to apps, Host web always refers to the site that the app is installed on. In your proposed situation, the token {HostUrl} would resolve to the latter: http://www.studentportal.com/sites/classroom2/subject1.
