Hi everyone,

we're using nginx/0.5.35

I want to set the Retry-After header for 503, but it isn't working.

This is how I tried:

error_page 500 502 504 /500.html;
error_page 503 /system/maintenance.html;
location /system/maintenance.html {
# Allow requests
}

location / {
if (-f $document_root/system/maintenance.html) {
add_header Retry-After 600;
return 503;
}

...
}

I've checked with curl -I -H and it's not showing Retry-After.

Any ideas?

Thanks,
Thomas
