TSHTTPTXNC...TREAMIDGET(3ts)

💖 TSHttpTxnClientStreamIdGet — the 3ts girlies know 💖

okay bestie, so this is a page from the Apache Traffic Server manual, section 3ts, and the function we're obsessing over today is TSHttpTxnClientStreamIdGet. yes it's a long name. no we're not shortening it. it's giving ✨verbosity✨ and honestly? iconic.

---

🌸 SYNOPSIS 🌸

#include <ts/ts.h>

TSReturnCode TSHttpTxnClientStreamIdGet(TSHttpTxn txnp, uint64_t *stream_id)

that's it, that's the whole signature, no cap 🫶

🦋 DESCRIPTION 🦋

so like,,, you know how every HTTP stream is out here living its own little life? yeah. this function retrieves the stream identification for the HTTP stream that your provided transaction is a part of. basically you hand it a transaction, and it tells you which stream that transaction is vibing in. 💅

the resulting stream identifier gets populated into the stream_id output parameter. so you pass in a pointer and it fills it up for you. very demure, very mindful.

now, the tea: this interface currently only supports HTTP/2 streams. only HTTP/2. not HTTP/1.1, not your situationship, just HTTP/2. 🌈

if you wanna get into the actual lore of HTTP/2 stream identifiers, go read RFC 7540 section 5.1.1. it's all there. the numbers, the odd/even thing, all of it. iykyk 📚

⚠️ heads up bestie: this API returns an error if the transaction you gave it is not an HTTP/2 transaction. so don't come crying to me when you pass it an HTTP/1.1 txn and it says no. it's not being mean, it's just being honest. 💀
