I try to set up a maintenance page for my rails app, using this snipplet.
error_page 503 /system/maintenance.html;
if (-f $document_root/system/maintenance.html) {
return 503;
}
This works as far as the presence of the maintenance.html causes the webserver to return a 503. But it returns the minimal nginx default error_page, not my maintenance.html. Why?
nginx 1.0.12 on Ubuntu 10.04 LTS
