TSHTTPHDRCOPY(3ts)

💖 TSHTTPHDRCOPY 💖

okay bestie, welcome to the TSHTTPHDRCOPY(3ts) page from the Apache Traffic Server manual 🦋 she's a tiny one but she's mighty, and she's about to save your whole entire day. sit down, hydrate, let's go ✨

🌸 NAME 🌸

TSHttpHdrCopy — copies the contents of the HTTP header located at src_loc within src_bufp to the HTTP header located at dest_loc within dest_bufp

like… it literally does exactly what it says on the tin. no cap 💅

---

✨ SYNOPSIS ✨

#include <ts/ts.h>

TSReturnCode TSHttpHdrCopy(TSMBuffer dest_bufp, TSMLoc dest_offset,
TSMBuffer src_bufp, TSMLoc src_offset)

yes the include is <ts/ts.h>, yes you need it, yes it goes at the top, periodt 🎀

---

🫶 DESCRIPTION 🫶

okay so here's the tea ☕ TSHttpHdrCopy() is out here working correctly even when src_bufp and dest_bufp are pointing at different Marshal Buffers. she does not care. she does not gatekeep. she copies across buffers like the icon she is 👑

but — and this is the important part, bestie, do not skip this — you must make sure that you create the destination HTTP header before you copy into it. create first, copy second. that's the order. the vibe check will fail otherwise 😭

NOTE: 🚨 TSHttpHdrCopy() appends the port number to the domain of the URL portion of the header. so if you copy http://www.example.com, what lands in the destination buffer is http://www.example.com:80 — the :80 is just there now, uninvited but very much present 🙈
