The default httpd.conf for FreeBSD contains this: #LoadModule session_module libexec/apache24/mod_session.so #LoadModule session_cookie_module libexec/apache24/mod_session_cookie.so #LoadModule session_crypto_module libexec/apache24/mod_session_crypto.so Enabling these and restarting the service appears to have resolved the issue.
