Yep, I realise it - that's exactly the bahaviour I expect...if the user has
hit the download limit, then the script uses the inner
if($has_hit_timeout_limit) stament (relating to the timeout), and keeps
doing so on each request until the timeout is over (since download value is
still over the limit for each request) - until at which point the inner if()
statement should reset the downloads to 0, and then download the file, and
increment the downloads column up by one again.
but for some reason, if i try to put $dl = true after the UPDATE (in the
inner if($has_hit_timeout_limit) statement), the download works, but the
UPDATE never happens, so i get an ever-increasing value for 'downloads' in
the db, and only 1 download, then timer, then 1 download, then timer, etc.
it really is bizarre! :(
