By dynamic you mean that you want to let user choose from *limited* set of
possible values for 'ip', right?
Limited is crucial here. You could just easily generate pagination rules using
other Cocoon pipeline instead of using
static file. This should work well and not harm your performance as long as you
do not break caching.
You should do this:
<map:transform src="cocoon:/pagination-rules?ip={request-param:ip}"
type="paginator">
and have following pipeline:
<map:match pattern="pagination-rules">
<map:generate src="pagination-rules-template.xml" type="jx">
<map:parameters name="ip" value="{request-param:ip}"/>
</map:generate>
<map:serialize type="xml"/>
</map:match>
The problem with this approach is that there is no place where we limit set of
possible values of ip parameter. However,
I hope it will give you starting point.
