Hi Out there,
I am searching for an solution for an issue to prevent Zend_cache to write a
lot of unnecessary Files if someone
Changes the request in a Loop.
Example:
for($id=0;$id<100000;$id++)
{
someGet(www.website.com?Unknown_nonesense=.$id);
}
As you may already expected I am using the querystring as ID for caching
I am currently thinking about some complicated solutions but maybe somebody
found a simple one *g
Some site Problems :
- No MVC (old Typo3)
- GET Params can change every day -> list of allowed Params is not
possible
Thanks guys
