TSHTTPTXNINFOINTGET(3ts)

💖 TSHTTPTXNINFOINTGET 💖

okay bestie, welcome to the TSHttpTxnInfoIntGet era — it's a lil function from the Apache Traffic Server manual, section 3ts, and she's lowkey iconic. let's get into it 🫶

---

✨ NAME ✨

TSHttpTxnInfoIntGet — the TSHttpTxnInfoIntGet API function. that's it, that's the name, no notes 💅

---

✨ SYNOPSIS ✨

#include <ts/ts.h>

TSReturnCode TSHttpTxnInfoIntGet(TSHttpTxn txnp, TSHttpTxnInfoKey key,
TSMgmtInt *value)

---

✨ DESCRIPTION ✨

so like, TSHttpTxnInfoIntGet() hands you arbitrary integer-typed info about a transaction, and which info you get is defined by TSHttpTxnInfoKey. no cap.

this API is gonna be part of a generic API umbrella that can support returning arbitrary info about a transaction using custom log tags. so it's giving "one umbrella to rule them all" energy 🌂✨

she works on multiple hooks depending on what info you're asking for, fr fr. like, cache-related info might only be available at or after the TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. so timing is everything, bestie — vibe check your hook first 😌

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

🎀 enum TSHttpTxnInfoKey 🎀

• enumerator TS_TXN_INFO_CACHE_HIT_RAM — this info is available at or after TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. a value of 1 means the response is returned from RAM cache 🍓. a value of 0 means 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 means the response is returned from RAM cache and is compressed (zipped and slayed 🔥). a value of 0 means otherwise.
• enumerator TS_TXN_INFO_CACHE_HIT_RWW — this info is available at or after TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. a value of 1 means the response is returned via Read-While-Writer functionality. a value of 0 means otherwise.
• enumerator TS_TXN_INFO_CACHE_OPEN_READ_TRIES — this info is available at or after TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. the value tells you the number of cache open read reattempts made by the transaction when a cache open read failed. like, how many times she tried again 😭
• enumerator TS_TXN_INFO_CACHE_OPEN_WRITE_TRIES — this info is available at or after TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. the value tells you the number of cache open write reattempts made by the transaction when a cache open write failed. persistence queen 👑
• enumerator TS_TXN_INFO_CACHE_VOLUME — this info is available at or after TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK hook. the value tells you the cache volume ID used for the cache object associated with the transaction. iykyk 📦

✨ RETURN VALUES ✨

the API returns TS_SUCCESS if the requested info is supported, and TS_ERROR otherwise. simple as that, no drama 💖
