If you want to use Saxon, start by looking at the sample servlet code that
comes with the product. You'll see that it caches compiled stylesheets (but
not source documents or results). You could modify the servlet if you need
to, to do other kinds of caching according to your application requirements.

Subject: Re: [xsl] XSLT on the server side
Thanks. But as i'm not a expert on that, that raises me a question.
The caching of both stylesheets and results of transformations are
made by who? The processor, like Saxon? Or the web server?
Now, i'm using a XSLTProcessor (in Sarissa) that allow for xslt
reusability, will it be someone like that?
I'm sorry if this questions are too dumb, but...

Whatever approach you choose, if you have any signicifant level of

than recompiling them on each request.

From the category of experiences worth remembering: When I
was a contractor
at Interleaf (and then an employee at Broadvision), I
worked on an XML-based
document management product (Bladerunner). The system
stored documents as
trees of nodes in a database. We found that users tended to
request the same
documents many times rather than each request being a new
document. So, we
cached the results of each query and the resulting
transformation and got a
significant performance boost (on the order of halving our
average response)
for our trouble.
So I suggest you give result caching a try, too. As ever,
YMMV (maybe your
users aren't as repetitive as ours were).
