Amos,
Once subtle and noteworthy difference between Squid-2 and Squid-3 which is
highlighted by this feature is that refresh_pattern applies its regex
argument against the Store ID key and not the transaction URL. So using the
Store-ID feature to alter the value affects which refresh_pattern directive
will be matched.<

a suggestion from a potential user (after my switch from 2.7 :-):
It might be a good idea to put some comment regarding this "feature" into
squid.conf. Preferably add something like this to the comments at
"refresh_pattern":
"Note, that refresh_pattern applies its regex argument against the Store ID
key and not the transaction URL, which means, in case of using a
StoreID-helper modifying the StoreID, refresh_pattern is matched against
this modified one."

We have these in the StoreID part of the docs since there is no chance of doing a refresh_pattern on StoreID without understanding the concept. If and only if you understand the meaning of StoreID you could cache objects efficiently.

To see the changes in the code alone could not provide the whole picture I had when thinking about the feature.

For testing purposes you test a real world scenario.
I know of couple methods of testing it but still From my point of view the best way is to test it in the level of headers + wget. browser may convince you that you are not caching enough so just ignore these browsers and use:
wget
curl
scripts

http://redbot.org/?uri=http%3A%2F%2Fwww1.ngtech.co.il%2F

The above are a set of tools which provides you a lot.
also notice the debug_options ALL,2 will help a lot also.

I just saw a small probably bug that you need to state the maximum object size of cache_dir object per cache_dir so try these on the way??
