diskCapacity is changing

[dqueffeulouatw]

Hi,

I have a weird behavior, I set diskCapacity to 0.5_1024_1024 to make some tests on limits. I check it in initWithMemoryCapacity: diskCapacity:diskPath: and it is good.
diskCapacity = 524288

Then I'm doing some access to fill the cache, and in the periodicMaintenance i found that diskCapacity is now 52428800.

Does anyone already seen this ?
As diskCapacity is not changed in SDURLCache, i'm wondering if NSURLCache is changing it and what rules it use.
