   * ** DLNA.ORG_FLAGS=01700000 plus 24 trailing zeroes**: ''dlnaVersion15Supported'', ''connectionStallingSupported'', ''backgroundTransferModeSupported'', ''streamingTransferModeSupported''
     * Supports DLNA version 1.5 (2006 spec)
+** HEAD Requests **
+Worth noting that the DLNA client sends three total HEAD requests.  They are identical, except the first one also includes a ''User-Agent'' string:
+<code>
+User-Agent: UPnP/1.0 DLNADOC/1.50
+</code>
+<code>
+Request Method: HEAD
+Request Url: /MediaItems/224.mkv
+User-Agent: UPnP/1.0 DLNADOC/1.50
+Host: 10.10.10.103:8200
+Accept: */*
+X-Av-Physical-Unit-Info: pa="Blu-ray Disc Player"
+X-Av-Client-Info: av=5.0; cn="Sony Corporation"; mn="Blu-ray Disc Player"; mv="2.0"
+Getcontentfeatures.Dlna.Org: 1
+</code>
+** realTimeInfo.dlna.org: DLNA.ORG_TLAG=* **
+minidlna always sends the header, safe to ignore it (see upnphttp.c)
