69660be0 | 40 | * We run a series of tests to determine if access will be permitted, and to do |

1220 | * | |
1221 | * The ClientRequestContext (aka calloutContext) class holds certain | |
1222 | * state data for the callout/callback operations. Previously | |
1223 | * ClientHttpRequest would sort of hand off control to ClientRequestContext | |
1224 | * for a short time. ClientRequestContext would then delete itself | |
1225 | * and pass control back to ClientHttpRequest when all callouts | |
1226 | * were finished. | |
1227 | * | |
1228 | * This caused some problems for ICAP because we want to make the | |
1229 | * ICAP callout after checking ACLs, but before checking the no_cache | |
1230 | * list. We can't stuff the ICAP state into the ClientRequestContext | |
1231 | * class because we still need the ICAP state after ClientRequestContext | |
1232 | * goes away. | |
1233 | * | |
1234 | * Note that ClientRequestContext is created before the first call | |
1235 | * to doCallouts(). | |
1236 | * | |
1237 | * If one of the callouts notices that ClientHttpRequest is no | |
1238 | * longer valid, it should call cbdataReferenceDone() so that | |
1239 | * ClientHttpRequest's reference count goes to zero and it will get | |
1240 | * deleted. ClientHttpRequest will then delete ClientRequestContext. | |
1241 | * | |
1242 | * Note that we set the _done flags here before actually starting | |
1243 | * the callout. This is strictly for convenience. | |
