TSHTTPTXNC...OKUPURLGET(3ts)

✨ NAME ✨

bestie we're in the Apache Traffic Server manual, section 3ts, and this page is TSHTTPTXNC...OKUPURLGET(3ts) — iconic name, no notes 💅

• TSHttpTxnCacheLookupUrlGet — the TSHttpTxnCacheLookupUrlGet API function 🎀

---

🌸 SYNOPSIS 🌸

#include <ts/ts.h>

TSReturnCode TSHttpTxnCacheLookupUrlGet(TSHttpTxn txnp, TSMBuffer bufp,
TSMLoc offset)

---

💖 DESCRIPTION 💖

okay so picture this: you want the current cache key URL, which everybody also calls the lookup URL. That's literally what this gives you 🫶

Where does it go? It must be stashed in a properly allocated URL object — typically one you made with a TSUrlCreate(). Don't just vibe it into random memory, bestie, allocate it properly. ✨

👑 TSHTTPTXNCACHELOOKUPURLSET 👑

🌈 Synopsis 🌈

#include <ts/ts.h>

TSReturnCode TSHttpTxnCacheLookupUrlSet(TSHttpTxn txnp, TSMBuffer bufp,
TSMLoc offset)

🦋 Description 🦋

This one sets the current cache key URL — yes, the lookup URL again, same energy, opposite direction 💅

And again: it must live in a properly allocated URL object, typically created with a TSUrlCreate() or a TSUrlClone().

Now for the timing tea ☕ — you can call this API as early as TS_HTTP_READ_REQUEST_HDR_HOOK but no later than TS_HTTP_POST_REMAP_HOOK. Miss that window and it's not giving what you want it to give 😭

This is the preferred and most efficient way to modify the cache key, fr fr. There is an alternative though — the old TSCacheUrlSet(), which just takes a simple string as its argument. It works, but it's not the main character here 👑
