52<p class="level0">Pass a char * as parameter, which should contain the specified range you want to retrieve. It should be in the format "X-Y", where either X or Y may be left out and X and Y are byte indexes. 
53<p class="level0">HTTP transfers also support several intervals, separated with commas as in <span Class="emphasis">"X-Y,N-M"</span>. Using this kind of multiple intervals will cause the HTTP server to send the response document in pieces (using standard MIME separation techniques). For RTSP, the formatting of a range should follow <a href="http://www.ietf.org/rfc/rfc2326.txt">RFC 2326</a> Section 12.29. For RTSP, byte ranges are <span Class="bold">not</span> permitted. Instead, ranges should be given in npt, utc, or smpte formats.
