I though you were using my code, now try with :
Code:
on *:SOCKREAD:download_*: {
  if ($sockerr > 0) echo -s error
  elseif (!$sock($sockname).mark) {
    var %read
    sockread %read
    if (%read == $null) sockmark $sockname 1
  }
  else {
    while ($sock($sockname).rq > 0) {
      sockread &file_d
      .bwrite $qt($remove($sockname, download_)) -1 -1 &file_d
    }
  }
}

alias download_file {
  sockclose $1
  sockopen $+(download_, $1) HOST-HERE 80
}

on *:SOCKOPEN:download_*: {
  if ($sockerr > 0) echo -s Error.
  else {
    sockwrite -n $sockname GET $+(/files/, $remove($sockname, download_)) HTTP/1.0
    sockwrite -n $sockname Connection: Keep-Alive
    sockwrite -n $sockname Host: HOST
    sockwrite -n $sockname
  }
}
