Not valid copy of object cached.

         Hello Squid users,

I would like to know why my Squid 2.0 RELEASE has cached
a non valid copy of requested object ?
Is this a normal behaviour of Squid 2.0 or have
I put something wrong in my squid.conf ?
 
I wrote this, 'cause I've tried to download a file (.exe) through Squid,
but squid has returned only 20% of the file,
i.e the file's real Content-Length is 1546856 bytes
and I've got 257772 bytes from the cache.
 
access.log:
==========
923991482.909 27000 raven.swh.sk TCP_HIT/200 257772 GET http://support.exe.sk/download/mbsap10.exe - NONE/- application/octet-stream
 
store.log:
==========
923991483.024 RELEASE 0200A5F3 200 923988947 923937039 -1 application/octet-stream 1546856/257415 GET http://support.exe.sk/download/mbsap10.exe

I would be glad, if someone could tell me how
to fix this problem.

Benarson.
