TSHTTPTXNISINTERNAL(3ts)

💖 TSHTTPTXNISINTERNAL(3ts) 💖

okay bestie, welcome to the 3ts corner of the manual, aka the Apache Traffic Server API zone ✨ this one's short and sweet and it answers exactly one (1) question: did we make this request ourselves, or did somebody else? 🦋

---

🌸 NAME 🌸

TSHttpTxnIsInternal — test whether a request is internally-generated 👀

---

✨ SYNOPSIS ✨

#include <ts/ts.h>

int TSHttpTxnIsInternal(TSHttpTxn txnp)

int TSHttpSsnIsInternal(TSHttpSsn ssnp)

---

💅 DESCRIPTION 💅

So like, two lil functions, both with the same energy:

• TSHttpTxnIsInternal() — tests whether a HTTP transaction was originated within Traffic Server 🫶
• TSHttpSsnIsInternal() — tests whether a HTTP session was originated within Traffic Server 🫶

that's it. that's the whole vibe. internal origin or not, no in-between 💀

---

🎀 RETURN VALUES 🎀

Both these APIs return a int, indicating whether the request was internal (1) or not (0) 👑

so: 1 = yeah girl we made it, 0 = nope, this came from outside. no cap 💖

---

🌈 EXAMPLES 🌈

the ESI plugin uses TSHttpTxnIsInternal() to ignore requests that it had generated while fetching portions of an ESI document 🙈 iconic behaviour honestly

static bool
checkForCacheHeader(const char *name, int name_len, const char *value, int value_len, bool &cacheable)
{

(yeah that's where the snippet cuts off in the original — we keep it exactly as it is, no editing the queen's handwriting 💅)
