The 'maximum_object_size' will just restrict what is *cached*, not the size of the object.

What you probably want is 'reply_body_max_size'.

See http://www.squid-cache.org/Doc/FAQ/FAQ_long.html#ss4.21 for the explanation, and http://squid.visolve.com/squid/squid24s1/tuning.htm#reply_body_max_size for a more detailed explanation.

set reply_body_max_size=2000 (KB) in your /etc/squid.conf

See the syntax and give in squid.conf file & restart the squid:

reply_body_max_size 512000 allow USER1

Now the USER1 able to download files of a maximum size of 512000 bytes (500 KB).

Note:
allow the USER1 also in squid.conf

You have to set reply_body_max_size header in squid.conf to achieve this.

reply_body_max_size bytes allow|deny acl acl

If you want to block specific users then,

# Please setup any of the authentication methods
acl USER2MB proxy_auth username username2
reply_body_max_size 2097152 allow USER2MB

Reconfigure your squid as,

./squid -k reconfigure.

Try it out.

Have you concidered using Hierachical Token Bucket (HTB) based bandwidth trotteling with the tc command instead? This might be what you are looking for.

It is really ingenious - I put it in place when I had a few users hogging the line all the time. If you do, prepare for a bit of reading to understand the concepts, but it is well worth it. For instance, start with this:
