🎀 NAME 🎀

cachemgr.cgi — Squid HTTP proxy manager CGI web interface

---

🌸 SYNOPSIS 🌸

http://your.server/cgi-bin/cachemgr.cgi

literally just open it in a browser, no cap 🌈

---

🦋 DESCRIPTION 🦋

So the cache manager (cachemgr.cgi) is a CGI utility that shows you statistics about the Squid HTTP proxy process while it's actually running. like, live, in real time, main character energy fr fr.

It's the convenient way to manage the cache and peek at statistics without logging into the server. no ssh, no terminal, just vibes ✨

💜 CONFIGURATION 💜

Configuration examples for many common web servers? They're in the Squid FAQ wiki, bestie. Go look:

https://wiki.squid-cache.org/SquidFaq

the config files 📁

• ./cachemgr.conf
• /etc/squid/cachemgr.conf

This is the access configuration file that defines which Squid servers may be managed via this cachemgr.cgi program. Every single line specifies a server:port followed by an optional description. yes, one per line. that's it.

The server name may contain shell wildcard characters such as *, [] etc. And a quick selection dropdown menu is automatically constructed from the simple server names — so cute, it builds itself 💅

Specifying :port is optional. If you don't specify it, the default proxy port is assumed. And if you write :* or :any? That matches any port on the target server. iconic.

🔥 SECURITY 🔥

okay listen up because this part is serious, no games 🙈

cachemgr.cgi calls the requested server on the requested port using HTTP and returns a formatted version of the response.

To avoid abuse it is recommended to configure your web server to restrict access to the cachemgr.cgi program. Like. Actually do it. Not me being dramatic, this is in the manpage. 🔒
