We therefore need a mechanism to allow byteranges1317 with a content-range not indicating the full length of the message.1318 (<xref target="header.content-range"/>)1319 </t>1320 <t>1321 Range request responses would become very verbose if all meta-data1322 were always returned; by allowing the server to only send needed1323 headers in a 206 response, this problem can be avoided.1324 (Section <xref target="status.206" format="counter"/>1325 and <xref target="header.if-range" format="counter"/>)1326 </t>1327 <t>1328 Fix problem with unsatisfiable range requests; there are two cases:1329 syntactic problems, and range doesn't exist in the document.
