[squid-users] Selective cache flush?

Is there a way to flush only certain items out of the Squid cache when
those item(s) are updated on the web server?

Let's say the web server DocumentRoot has:

/content/1/a.txt
/content/1/b.txt
/content/2/a.txt
/content/2/b.txt

If something in /content/1/ is changed, I'd like to be able to flush
those items (everything in /content/1/ would be OK since it's likely
that one change would involve several files) without affecting
/content/2/ or anything else in the cache.
