I think that the problem comes down to whether the server you are requesting from honours the Range: header. The maz_size parameter uses that to request a the first max_size bytes of the file. If the server doesn't honour this (I believe optional, but I couldn't find the appropriate RFC) header, then you will likely get the lot. You might try the HEAD command, but that isn't always honoured either. If this is a show stopper to your application, you could consider hacking LWP::Protocol::http.pm/request(). It ought to be possible to cross-reference any Range: header specified on the request and bottle out of the read loop early, or perhaps better, read and discard content greater than requested, but your a brave man if you decide to mess with this stuff:) If neither the HEAD requests nor the Range: header are being honoured by the server, it might be better to nag the sysops of that server to enable/upgrade them. Examine what is said, not who speaks.

When he states that something is impossible, he is very probably wrong. 2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible 3) Any sufficiently advanced technology is indistinguishable from magic.
