I want to set a page of subsite as home page of its parent site. Is it possible ?
You can use PowerShell. Something like this:
$web = Get-SPWeb -Identity http://yourportalurl.ru $folder = $web.RootFolder $folder.WelcomePage = "filter/Lists/presidents/AllItems.aspx" $folder.Update()
Url of WelcomePage must be relative url (not started with "/"). In my example I set list view of subsite.
