> Transaction &
> utils::internal::getTransaction(TSHttpTxn ats_txn_handle)
> {
> Transaction *transaction = static_cast<Transaction
> *>(TSHttpTxnArgGet(ats_txn_handle, TRANSACTION_STORAGE_INDEX));
> if (!transaction) {
> transaction = new Transaction(static_cast<void *>(ats_txn_handle));
> LOG_DEBUG("Created new transaction object at %p for ats pointer %p",
> transaction, ats_txn_handle);
