CGI::Se...:db_file(3)

💾 CGI::Session::Driver::db_file(3) — a CGI::Session driver for BerkeleyDB via DB_File

okay so real talk, this page lives in the User Contributed Perl Documentation section of your man pages, and it's about the tiny little driver that keeps all your session data cozy inside a BerkeleyDB file. let's get into it 🫶

---

✨ SYNOPSIS ✨

like, here's the vibe in code form, bestie — copy-paste ready:

$s = CGI::Session->new("driver:db_file", $sid);
$s = CGI::Session->new("driver:db_file", $sid, {FileName=>'/tmp/cgisessions.db'});

that's it. that's the whole mood. 💅

🌸 DESCRIPTION 🌸

so db_file stores your session data in a BerkeleyDB file, and it does it using DB_File — the Perl module. iconic behavior honestly.

the way it works: every single session lives in one shared file. not one file per session, no ma'am, all of them together in one spot. you point at that file with the FileName driver argument, literally just like in the example up there. ⭐

and if you don't pass FileName at all? no worries, it's got a default: /tmp/cgisess.db — or whatever the equivalent of that is on a non-UNIX system. she's flexible. 🌈

lowkey the best part: if the directory hierarchy leading to the file doesn't exist yet, it gets created for you. no manual mkdir, no tears. 😭

there's also a UMask option this module takes — it gets used whenever DB_File has to go ahead and create the database file for you. by default, the umask is 0660. periodt. 🎀

💜 quick reminder bestie: everything above is straight from the page, i didn't invent a single flag. the defaults are real defaults, the paths are real paths, and the umask is genuinely 0660. no cap.

and that's the whole page!! this beauty shipped as part of perl v5.42.2, dated 2026-07-28, filed under that CGI::Session::Driver::db_file(3) header at the top. go forth and store those sessions, main character 💖✨
