Byteserving, Range: headers and assorted foo.

[Kevin Murphy]

I'm attempting to use the byteserving methods of Apache::File, but I'm
getting strange results. Apache 1.3.9, mod_perl 1.21. 

Here's the request (entered via telnet to port 80):

GET /image/1000/foo.gif HTTP/1.1
Host: www.eorbit.net
Range: bytes=0-50

Here's a code snippet:
.
.
.
  unless ($r->header_only)
  {
    my $rangestatus = $r->set_byterange;

    $log->debug("Byte ranges?: $rangestatus");

    if (!$rangestatus)
    {
      $log->debug("Whole file request");
      $r->send_fd($fh);
    }
    else
    {
      $log->debug("Byte range request");
      my $head_length= length($v2Tag);
      while(my($offset, $range_length) = $r->each_byterange)
      {                      
         {do byteserving foo}
       }          
     }
   }
.
.
.

The problem? Doing a dump of $r->headers_in shows that the Range:
header is is present, but when I call $r->set_byterange, it returns
zero, regardless of whether the Range: header is there or not.

Am I constructing my request badly, or is there something else I'm 
missing? I put this code together from some sample code that Doug 
posted to the list some time ago, and there doesn't seem to be any
further documentation on this portion of the request object.
