TSHTTPHDRLENGTHGET(3ts)

💖 TSHTTPHDRLENGTHGET 💖

okay bestie, welcome to the TSHTTPHDRLENGTHGET(3ts) page — yes that's the whole manual name, yes it's a mouthful, and yes we're getting through it together 🫶 this is a section 3 function from the Apache Traffic Server crew, so grab your strawberry drink and let's go ✨

---

🌸 NAME 🌸

TSHttpHdrLengthGet — it's the TSHttpHdrLengthGet API function, periodt 💅

---

🎀 SYNOPSIS 🎀

lowkey the whole thing is just this:

#include <ts/ts.h>

int TSHttpHdrLengthGet(TSMBuffer bufp, TSMLoc mloc)

that's it, that's the vibe 🌈

---

✨ DESCRIPTION ✨

so what does it do, you ask? it returns the length in characters of the HTTP header that bufp and mloc are pointing at 👑

and like — important — that header has to be a valid HTTP header. no fake ones, no half-built ones, it's giving "must specify a valid HTTP header" and we respect that fr fr 💀

where do those bufp and mloc values usually come from tho? normally you'd have snagged them earlier from one of these iconic little calls:

• TSHttpTxnServerReqGet()
• TSHttpTxnClientReqGet()
• TSHttpTxnServerRespGet()
• TSHttpTxnClientRespGet()

or you got them from calls that spin up a brand-new HTTP header, like TSHttpHdrCreate() 🦋

either way, main character energy: you already have your bufp and your mloc, and this function just tells you how many characters long that header is. obsessed 💖

ngl bestie, don't be passing it a non-header and expecting magic — the docs literally say it "must specify a valid HTTP header", so vibe check your pointers first 🙈
