My problem is that caching is not used if any GET parameter is
present, but we expect high traffic from links bearing this parameter
(think referral/affiliation programs, etc.) so we need caching.
Quoth the Book, Chapter 12:
> Actions called with a POST method or with GET parameters are not cached.
So my question is: how can I override this safeguard so that the cache
filter believes there was no GET parameter?
My filter executes before the cache filter, and once it does its
processing, I can safely get rid of the parameter (it has no bearing
on page content). But I haven't found a way to do this that will fool
the cache filter.
I have tried:
class myFilter extends sfFilter
{
public function execute($filterChain)
{
$request = $this->getContext()->getRequest();
$user = $this->getContext()->getUser();
// ...processing...
$request->getParameterHolder()->remove('my_param');
$filterChain->execute();
}
}
