In a WebApp with diffrent site collections and subsites, I would like to add a link on the custom master page of all sites to the WebApp Url. (This Url is corresponding with a home/top site collection)
E.g. http://mysp2010farm/sitecollection1/site1/default.aspx is a site and in my custom master page I need a link with href="http://mysp2010farm"
This needs to be done dynamic and not hardcoded.
