26ac0430 | 13 | * |
69660be0 | 14 | * We run a series of tests to determine if access will be permitted, and to do |
15 | * any redirection. Then we call into the result clientStream to retrieve data. | |
16 | * From that point on it's up to reply management. | |

1703 | * doCallouts() - This function controls the order of "callout" | |
1704 | * executions, including non-blocking access control checks, the | |
1705 | * redirector, and ICAP. Previously, these callouts were chained | |
1706 | * together such that "clientAccessCheckDone()" would call | |
1707 | * "clientRedirectStart()" and so on. | |
1708 | * | |
1709 | * The ClientRequestContext (aka calloutContext) class holds certain | |
1710 | * state data for the callout/callback operations. Previously | |
1711 | * ClientHttpRequest would sort of hand off control to ClientRequestContext | |
1712 | * for a short time. ClientRequestContext would then delete itself | |
1713 | * and pass control back to ClientHttpRequest when all callouts | |
1714 | * were finished. | |
1715 | * | |
1716 | * This caused some problems for ICAP because we want to make the | |
1717 | * ICAP callout after checking ACLs, but before checking the no_cache | |
1718 | * list. We can't stuff the ICAP state into the ClientRequestContext | |
1719 | * class because we still need the ICAP state after ClientRequestContext | |
1720 | * goes away. | |
1721 | * | |
1722 | * Note that ClientRequestContext is created before the first call | |
1723 | * to doCallouts(). | |
1724 | * | |
1725 | * If one of the callouts notices that ClientHttpRequest is no | |
1726 | * longer valid, it should call cbdataReferenceDone() so that | |
1727 | * ClientHttpRequest's reference count goes to zero and it will get | |
1728 | * deleted. ClientHttpRequest will then delete ClientRequestContext. | |
1729 | * | |

1731 | * the callout. This is strictly for convenience. | |
