| This plugin sets up a callback to a continuation whose |
| handler function creates a thread. |
| |
| TSPluginInit uses TSHttpHookAdd to create a |
| continuation that is called back after the HTTP |
| origin server DNS lookup (the hook is |
| TS_HTTP_OS_DNS_HOOK). The handler function |
| for the continuation is thread_plugin. |
| |
| The thread_plugin function creates a thread using |
| TSThreadCreate(), passing it the reenable_txn function |
| as follows: |
| TSThreadCreate(reenable_txn, edta); |
| |
| The thread runs the reenable_txn function, which simply |
| reenables the HTTP transaction using TSHttpTxnReenable(). |
| The thread is automatically destroyed when the function |
| returns. |
