Microsoft have released the latest update for SharePoint Enterprise Server 2013! The main fix for this update is:
- SharePoint Server 2013 is unable to crawl external sites that block HTTP 1.0 request. In this case, SharePoint would receive 403 HTTP response code from external sites. This update will enable SharePoint Server 2013to crawl such external sites by sending HTTP 1.1 request instead of HTTP 1.0 request.
