Any reason not to?
Thanks,

Santiago,
Will look into it. So far we have not implemented Cacheable for ResourceReaders.
Thanks,

For the sake of completeness :), I had already observed (and it is still
there) the following traces regarding css files (both in jakarta site
and here in slides.

Santiago,
Have fixed the problem. Can you please try it out? Now the checks take into account the request
params also.
Does anyone else see any other problems?

Yes I know and thus have proposed to have one without anything because

Giacomo,
The parameters from sitemap and parameters from request have been in the TraxTransformer since day
one :) Yes, i will cook you up a "Pure" TraxTransformer tomorrow.

It is already populated with request.parameters and thus you can put in
what you want as long as we have a Pure- or SimpleTraxTransformer
without any additionals.

I haven't checked the slides.

Parameter, Request or what ever? I really like to have a simple one

Well, IIRC the interface used is the org.apache.cocoon.components.store.Store.
There are currently two implementation MemoryStore and FilesystemStore (I don't
know the details). As they are Avalon components specified in the cocoon.xconf
file they can be configured at will.
And, yes, a independant and adaptive Object Store for C2 will be very welcome.

We are considering the Cocoon2 store as a portlet cache for Jetspeed.
Some time ago we used the Cocoon1 store for this purpose. Currently we
are using the Turbine cache, but I like a lot Stefano's proposal (which
I think will be eventually in here) and the key algorithm.
Currently, the String operations involved in constructing jetspeed's
keys and checking for equality is contributing a substantial runtime
overhead to us. So the key approach would also be welcome.
We have a different cache (urlmanager) which could benefit Cocoon,
specially when news syndication come into play. I am currently
implementing it afresh, as the current code base is ugly and messy. This
cache takes care of storing external resources in disk.
I have been playing with the idea of having a multilevel disk and memory
cache, one that would keep used urls in memory, while having the rest on
disk. The same could be applied to other (serializable) objects.
I will definitely give a look to this code.
Do you know if I could use the store without heavy dependencies? which
dependencies (jars, config files) would I need?

Not really, it's quit the same. The only different are the higher mountains.

Would be cool. Can I assign your name with this issue into the todo list
:) ?

I'm still there and watching cocoon growing :-). You dont' t have to
apologize . It's always hard to get involved in so large projects and I have
to do a lot of work at business, too.
Yes my component is configurable. Currently in two ways:
* The cached objects have a configurable "lifecycle". If the "lifecycle" of
a object is over, it "dies".
* Also could the number of objects in the cache be limited. If the Limit is
reached the last object in the cache will be removed.
* there are also lot other possibilities, like combination of some caching
rules (like LFU / MRU) and so on.
My solution is a combination between a LinkedList and a HashMap. Both are

Sounds good. Mhhhh... maybe a solution like Squid or something else. I will
keep an eye on this proposal.
In the mean time, I try to get an overview over cocoon and cocoon2 :-) and I
hope I can support in the nearer future...
So long

Well, it's a component. We can later on write a more sophisticated Store to use.
There has been a contribution from a Austrian guy (Froehlich ?) for a MRUStore
recently. Maybe this component can be configured to limit the storage used. Has
anybody had a look at it (sorry to that guy if we have not take it so far into
consideration, but you've seen we are working very hard on different frontiers
:)
A possible final solution could be a Store that keeps frequently used cache
object in memory an swaps out others to the file system.

No real objection from me - the only problem I see right now might
be the memory consumption of the cache as nearly every request
is cached in memory.
