For example, cache related info may be available only at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook.

The *TSHttpTxnInfoKey* currently supports the below integer-based info about a transaction

- **enum TSHttpTxnInfoKey**

    This info is available at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook. A value of **1** indicates that the response is returned from RAM cache. A value of **0** indicates otherwise.

  - **enumerator TS\_TXN\_INFO\_CACHE\_COMPRESSED\_IN\_RAM**

    This info is available at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook. A value of 1 indicates that the response is returned from RAM cache and is compressed. A value of 0 indicates otherwise.

    This info is available at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook. The value indicates the number of cache open read reattempts made by the transaction on cache open read failure.

  - **enumerator TS\_TXN\_INFO\_CACHE\_OPEN\_WRITE\_TRIES**

    This info is available at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook. The value indicates the number of cache open write reattempts made by the transaction on cache open write failure.

  - **enumerator TS\_TXN\_INFO\_CACHE\_VOLUME**

    This info is available at or after *TS\_HTTP\_CACHE\_LOOKUP\_COMPLETE\_HOOK* hook. The value indicates the cache volume ID used for the cache object associated with the transaction.
