SPContnt.aspx - Manage wepparts in a page

Sometimes we need to manage(close, reset and delete) the existing webparts in the SharePoint page, but we could not use the EDIT page option (due to the exception issues in the wep parts). This is an application page called SPContnt.aspx. It takes one parameter url (full or relative path of the page) in the query string. So It would look something like

http://server/site/_layouts/spcontnt.aspx?url=http://server/site/default.aspx

This brings you to a page that will allow you to Close, Reset, and Delete Web Parts from the page.
