38 | * General logic of request processing: | |
26ac0430 | 39 | * |
69660be0 | 40 | * We run a series of tests to determine if access will be permitted, and to do |
41 | * any redirection. Then we call into the result clientStream to retrieve data. | |

1464 | * together such that "clientAccessCheckDone()" would call | |

1466 | * | |
1467 | * The ClientRequestContext (aka calloutContext) class holds certain | |
1468 | * state data for the callout/callback operations. Previously | |
1469 | * ClientHttpRequest would sort of hand off control to ClientRequestContext | |
1470 | * for a short time. ClientRequestContext would then delete itself | |
1471 | * and pass control back to ClientHttpRequest when all callouts | |
1472 | * were finished. | |
1473 | * | |
1474 | * This caused some problems for ICAP because we want to make the | |
1475 | * ICAP callout after checking ACLs, but before checking the no_cache | |
1476 | * list. We can't stuff the ICAP state into the ClientRequestContext | |
1477 | * class because we still need the ICAP state after ClientRequestContext | |
1478 | * goes away. | |
1479 | * | |
1480 | * Note that ClientRequestContext is created before the first call | |
1481 | * to doCallouts(). | |
1482 | * | |
1483 | * If one of the callouts notices that ClientHttpRequest is no | |
1484 | * longer valid, it should call cbdataReferenceDone() so that | |
1485 | * ClientHttpRequest's reference count goes to zero and it will get | |
1486 | * deleted. ClientHttpRequest will then delete ClientRequestContext. | |
1487 | * | |
