Shouldn't that be 536870912 ? Which is 512mb.
Hello Agilehost Sales
I agree with you that 536870912 would look better here and fixed this.
In general, 512mb isn't an obligatory value here. The main idea is that the limit should be more that the response body and this value is individual for different websites/installations.
