The length is always correct.

ZIP files: CRC Error
EXE files: errors when running them (if standalone programs) or when
installing them (like Adobe Acrobat Reader 6).

I did, and as I mentioned before, nothing changed. My parent proxy
(which was my main proxy, until I dediced to put another local proxy
here at my offce) seems still to cause corrupted downloads...

Mainly BIG files ( about every file bigger than 4/5MB), therefore ZIPs
and EXEs.

The last one, "application/octet-stream".

I can't get the parent proxy's log files, but mine is like:

1066382936.928 94247 10.167.211.11 TCP_MISS/200 18033719 GET

application/octet-stream
