[squid-users] How does Squid prevent stampeding during a cache miss?

For example, put Squid as a reverse proxy mode to
http://www.example.com/heavyduty.php (expire set to 1 hour, need 10s
to generate).

When the file is just expired, large amount of clients (e.g. 10K)
request for this file reached the Squid at the same time.

Are there any heuristics performed by Squid to avoid forwarding all
the 10K requests to the upstream?
