phpMyAdmin under Varnish

Add the below in the Varnish VCL file, under sub vcl_recv

if (req.url ~ "(phpMyAdmin|phpmyadmin|phpMyAdmin/setup)") {
return (pass);
}

Than test VCL

# varnishd -C -f /etc/varnish/default.vcl

…and if all is good

# service varnish reload

NOTE: sometimes, altering phpMyAdmin auth method in /etc/phpMyAdmin/config.inc.php from cookie to http

Varnish – basic notes 

ACLs: /etc/varnish/default.vcl

Memory usage:
grep VARNISH_STORAGE_SIZE /etc/sysconfig/varnish

Check how much memory can use: (check last parameter in the output line)
