Hi, I need hide real links from users, i write such script, but i'n not support resume downloading .... here my script:
#!/usr/bin/perl $| = 1; use strict; use Date::Format; use CGI qw(Fatalstobrouser); my $filename = "Proklate2.avi"; my $path = "/tmp/upload/"; unless ( -e $path . $filename ) { print STDERR "No such file! $path$filename"; return 0; } my @finfo = stat("$path$filename"); my $filesize = $finfo[7]; my $mfile = $finfo[9]; my $filemtime = time2str( "%D, %d %M %Y %H%i%s %T", $mfile ); open FH, "< $path$filename" or die "Can't open $path$filename: $!"; my $contentSize; $| = 1; my $HTTP_RANGE = $ENV{HTTP_RANGE}; if ($HTTP_RANGE) { my $range = $HTTP_RANGE; # bytes 7210589-14411430/14411431 $range =~ m/bytes=(\d+)-/; $range = $1; $contentSize = $filesize - $1; warn("cont size is $contentSize and range is $range\n"); my $p1 = $filesize - $contentSize; my $p2 = $filesize - 1; my $p3 = $filesize; seek( FH, $p1, 0 ) or die "Couldn't seek to $p1: $!\n"; print STDOUT "HTTP/1.1: 206 Partial Content\r\n"; print STDOUT "Last-Modified: $filemtime\r\n"; print STDOUT "Cache-Control: None\r\n"; print STDOUT "Pragma: no-cache\r\n"; print STDOUT "Accept-Ranges: byte\r\n"; print STDOUT "Content-Disposition: attachment; filename=\"$filena +me\"\r\n"; print STDOUT "Content-Range: bytes " . $p1 . "-" . $p2 . "/" . $p +3."\r\n"; print STDOUT "Content-Length: $contentSize\r\n"; print STDOUT "Proxy-Connection: close\r\n"; print STDOUT "Content-type: application/octet-stream\r\n"; print STDOUT "\r\n"; } else { $contentSize = $filesize; print STDOUT "Last-Modified: $filemtime\r\n"; print STDOUT "Cache-Control: None\r\n"; print STDOUT "Pragma: no-cache\r\n"; print STDOUT "Accept-Ranges: bytes\r\n"; print STDOUT "Content-Disposition: attachment; filename='$filenam +e'\r\n"; print STDOUT "Content-Length: $contentSize\r\n"; print STDOUT "Content-type: application/octet-stream\r\n"; print STDOUT "Proxy-Connection: close\r\n"; print STDOUT "\r\n"; } binmode FH; my $buffer; STREAM: while ( read( FH, my $buffer, 65536 ) ) { last STREAM unless print STDOUT $buffer; } close FH;
But log of sended headers:

Than script sends 200 OK response, but I need 206. Can you please advice how to make workaround for this?
