HTTP Header Variables
HTTP_RANGE This variable specifies the number of bytes (or a range of
bytes if the range is indicated) a web client is able to
retrieve.
Format:
bytes=number-of-bytes
or
bytes=range-of-bytes
where
range-of-bytes
consists of a starting value and an ending value
separated by a hyphen (-); omit the starting value
if you want the web client to be able to retrieve
the last number of bytes specified by
range-of-bytes.
Examples:
bytes=0-499
specifies a range from 0 to 499
bytes=-250
specifies the previous 250 bytes
HTTP_USER_AGENT This variable identifies the web client software being used
to access the server.
Format:
browser-name/version
Example:
