Subject: Moved AccessCheck object creation and check starting to AccessCheck::Start.
X-Git-Tag: SQUID_3_1_0_1~49^2~302^2~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=abd4b6119cfac937348f13c4d7301ec0662d5bcb;p=thirdparty%2Fsquid.git

Moved AccessCheck object creation and check starting to AccessCheck::Start.
We may be able to simplify the callers further by migrating to the AsyncJobCall
interface for callbacks.
