Christian,
When we've had the need to cache a query, we just throw the result (as a
DOM object) into the sesssion. I'm including the sample pipeline. I'll
typicailly aggregate the results of this with something else (usually a
dynamic query) and I'm all set. When I want to clear the cache, the
I just skimmed through the mailing list to find ideas of how to cache a
pipeline starting with a request generator and later on passing data
through the SQLTransformer.
Did you or anybody else follow up on this idea?
NB: Caching of the request generator would probably also need to cache
request

If you use a source the only way to pass a parameter is the source
string itself (at least AFAIK). I'm not sure if something like

Hi,
I have a 16MB XML file. I want to know how to cache it.
It is used in the generator.
1. Do i need to restart tomcat once i change the
cocoon.xconf file
2. Does the generator need additional paramerters?
3. Is there anything wrong with cocoon.xconf
I tried the standard things that I found

If you're doing the SQL queries in a custom component (generator,
transformer) you can use Cocoon's caching system. Have you class
implement Cachable, and in the generateValidity() method you can return
an object with the last modification date of the database.

I got sidetracked and am now trying (once again) to get Cocoon2 running on
our Linux server. We are using Cocoon 2.0.2, Tomcat 3.2.2 (with Apache),
RedHat 7.1, and IBM JDK 1.3.0.
My last post (12 Apr 2002) left me with this error message on Cocoon

RequestGenerator *should* cache. Give me a good reason why it shouldn't
have caching!

What I'd like to see is a flag that I can use to mark a map as cached and
the ability to specify a time-out.
For example:
In this case, what'ever is returned by "test", no matter what it is or how
it was generated would be cached for 300 seconds. The map wouldn't even try

I did it once with Cocoon 1.8. It works but don't expect high figures:
we are working on it, but as of now there is almost no way to cleverly
