Here is the problem description, what solution might Squid or other
cache tools provide?
Some websites serve huge files, usually movies or binary distributions.
Typically a client issues byte range requests, which are not cacheable
as separate objects in Squid.

Is there a way to ignore URI query terms when forming store keys?
Maybe some rule or extension?
In the Squid code it could look something like:
{ char *p = strchr(uri, '?'); if (p) *p = '\0'; }
But the only code like this deals with strip_query_terms.
This rule only affects logging, not storing.
I'm observing very high Squid CPU load, which negatively affects performance.
Enabling debug_options ALL,9 for a few seconds shows this extremely
frequent loop -- Squid is doing only this millions of times:

There are 7 fork()s for unlinkd/diskd helpers. Can these fork()s
affect profiling info?

Hi,
The problem: on a certain origin content, Squid reaches 100% CPU
periodically, every 10 minutes, so the cache service suffers.
Any clues where to look? Maybe this problem and its solution are known?
The CPU load pattern is something like this, minute-by-minute:
40%, 40%, 60%, 80%, 99%,
the Squid artifact of inserting an Expires
header.
Is there a Squid configuration ability to do so? If not, what would
be the right way to do it in my local code branch?

I've tried to set an exact time-to-live (override origin cache
control) in Squid (2.4 STABLE6) configuration by refresh_pattern,
e.g.:
refresh_pattern 30_minutes_cache_control_url 15 0% 15
override-expire ignore-max-age
Observed: URL is matched (in log), but objects still cached for 30
10 matches
