I installed the PHP files in my server but my tests failed. I still have to solve this, but I'm a newbie so I do not know if I will succeed.

Meanwhile, trying to download just a couple of tiles (NY City), the cache was filled with 97 Mb. If this was for just a petition, I think it would require a lot of space. Is there any way to limit the cache size, for instance, to the 10 Gb zabbensx offers?
