The redirector interface in Squid is optional, but quite powerful. It
can be used to
a) Redirect users to other sites, such as more closeby mirrors.
b) External access control
c) Many other things also possible...

Because the core expects to have a StoreEntry, and errors are also
negatively cached in memory.

The store manager is a somewhat moving target, but we can try..
There are a number of different interfaces to or related to the store
manager:
* Interface for finding objects in the cache
* Interface for protocols to store information
* Interface between store manager and "filesystems"
* Interface used to control removal policies
* Interface to read data
which one of these interfaces needs more information first?
And please keep discussions on squid-dev@squid-cache.org, the list
existing for the sole purpose of discussion about the Squid code.
