speed When used in a request, this token specifies a speed-up factor, in which the client is requesting that the server apply its normal transmission rate. When used in a response, this token specifies the speed-up factor that the server is intending to apply to its normal transmission rate. The normal transmission rate is defined as the sum of the average bit rates of the ASF streams (2) that will be transmitted. If an token has been specified in the request, this MUST NOT affect the determination of the normal bit rate. This token is defined for use only in requests sent to a server with a version greater than or equal to 5.0 (as specified by the server in the header).<36> The value MUST be a real number in the range from 1 through 4,294,967,295. The syntax of the token is defined as follows. speed = "Speed=" 1*DIGIT["." 1*3DIGIT] In the example below, the value indicates 5 times faster than real time: Pragma: stream-offset This token specifies a byte offset from which playback begins. The byte offset is measured from the beginning of the ASF file and is expressed as two decimal numbers separated by a colon. The value for stream-offset MUST match the start of a packet within the ASF file. Each of the two numbers MUST be in the range from 0 through 4,294,967,295. The first number gives the most significant 32 bits of the byte offset and the second number gives the least significant 32 bits of the byte offset. This token is defined for use only in requests sent to a server. The syntax of the stream-offset token is defined as follows. stream-offset = "stream-offset=" 1*10DIGIT ":" 1*10DIGIT The following is an example to start playing at 1,024 bytes into the file. Pragma: stream-offset=0:1024 The following is an example of ignoring stream-offset. Pragma: stream-offset=4294967295:4294967295 stream-switch-count This token specifies the number of stream-switch entries in the token.
