It's a bit of a voodoo hack. Squid has user caps, or global caps. The user
cap can be based on IP or username or some external_acl_type result.

Option 1) the simple one
  pool all requests with files over a certain size. There are gaps which
open when the file has unknown length.

option 1) the big hack.
 Using a class 5 delay pool with external_acl_type tag= that only
'matches' when bandwidth pipe usage is above a threshold.

The two can be combined of course, for a closer catch of problem requests.

Some research is ahead if you choose the class 5 tag pool to discover
exactly how its configured and how it works. My knowledge of it is
currently limited to whats written in the config manual.
