解説

records.config に設定されるいくつかの値は特定のトランザクションにおいて変更することが可能です。これらの関数はトランザクション用に格納された設定値を変更すること、つまりトランザクションが実際に処理する際の値を変更するのとまったく同じではないことに注意することが大切です。その重要な影響は値がトランザクションで使用される前に変更されていなければならないことです。使用された後だった場合、変更は何の効果も持ちません。

すべての ...Get 関数は value 引数で示された記憶領域に内部値を格納します。文字列では length* は文字列の長さを受け取ります。

値は列挙型 TSOverridableConfigKey で特定されます。文字列値は最初に TSHttpTxnConfigFind() に渡すことで間接的に使用でき、この関数は文字列が上書き可能な値に一致した場合にキーとデータ型を返します。

例

トランザクションバッファリング制御 を high water マーク 262144 と low water マーク 65536 で有効化します。

int callback(TSCont contp, TSEvent event, void* data)
{
   TSHttpTxn txnp = static_cast<TSHttpTxn>(data);
   TSHttpTxnConfigIntSet(txnp, TS_CONFIG_HTTP_FLOW_CONTROL_ENABLED, 1);
   TSHttpTxnConfigIntSet(txnp, TS_CONFIG_HTTP_FLOW_CONTROL_HIGH_WATER_MARK, 262144);
   TSHttpTxnConfigIntSet(txnp, TS_CONFIG_HTTP_FLOW_CONTROL_LOWER_WATER_MARK, 65536);
   return 0;
}
