💖 TSSSLCLIENTCERTUPDATE 💖

okay bestie, welcome to the 3ts manual page for TSSslClientCertUpdate — a lil function from Apache Traffic Server that does exactly what it says on the tin: it swaps out your TLS client certs while everything's still running. no restart, no drama. we love a hot-swap moment. ✨

🌸 NAME 🌸

TSSslClientCertUpdate — traffic Server TLS client cert update 🎀

like literally it updates the TLS client cert. that's the whole vibe. that's the assignment. 💅

✨ SYNOPSIS ✨

#include <ts/ts.h>

TSReturnCode TSSslClientCertUpdate(const char *cert_path, const char *key_path)

so you're gonna pull in ts/ts.h first, obviously, and then you get to call this thing with two paths. that's it. that's the whole entry point. 🦋

💜 DESCRIPTION 💜

okay so here's the tea. TSSslClientCertUpdate() updates the client certificates that you already configured — either over in sni.yaml or via proxy.config.ssl.client.cert.filename. it's not out here creating new configs, it's refreshing the ones you already committed to. main character energy but make it existing main character energy. 👑

ngl the one thing you have to get right: cert_path has to be an exact match to whatever you wrote in your configuration. exact. like, don't be cute with it, don't rename it, don't shuffle the slashes around. it's giving "the config and the call have to be the same string," fr fr. 🫶

and the return value? TSSslClientCertUpdate() hands you back TS_SUCCESS only if cert_path actually exists in the configuration and it got reloaded to update the context. so if you get TS_SUCCESS, congrats bestie, the context is updated. if you don't — well. that path wasn't in the config, or the reload didn't happen. no cap. 😭

lowkey important: success here is a two-part deal — path exists and reloaded. one without the other is not a success. read the return value like it owes you money. 💀

2026, dev@trafficserver.apache.org — that's the team behind all this. respect the architects. 🌈

and that's the whole page, bestie!! this one came straight out of version 9.2, dated Feb 12, 2026, from your friends at Apache Traffic Server. go forth and update those certs, you absolute icon. 💖✨🌸🦋💅🫶👑
