 My **working notes** on looking at DLNA headers.  Specific to my setup (minidlna, Sony BDP) only -- using the wiki as a location to keep notes.  Not meant to be useful for people who are not me. :) My **working notes** on looking at DLNA headers.  Specific to my setup (minidlna, Sony BDP) only -- using the wiki as a location to keep notes.  Not meant to be useful for people who are not me. :)

 +  * ** DLNA.ORG_OP=01 ** HTTP Range requests supported
 +  * ** DLNA.ORG_CI=0 ** media is not transcoded
 +  * ** 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)
