I've got a sharepoint site with multiple site collections.
/ site collection:
http://mysite/ <--- root site in `/` site collection http://mysite/subsite1 http://mysite/subsite2
/sitecol1 site collection:
http://mysite/sitecol1/ <-- root site in `/sitecol1` site collection http://mysite/sitecol1/mysubsiteinsitecol1 http://mysite/sitecol1/mysubsiteinsitecol2
Using rest api, how can I given
http://mysite/sitecol1/mysubsiteinsitecol2 determine what root site colleciton it is from?
Forgot to mention - I need this to work on SharePoint 2010, 2013 and 2016.
