NGINX_Apache + Varnish problems

[an4rei]

Hello! I've succesfully configured NGINX+APACHE+VARNISH as below:
nginx(listens 1424) ->proxies to 8080(Apache)
nginx(listens 443) -> proxies to Varnish(port 80) -> Varnish gets data from backend port 1424(nginx).

I'm also using a CDN so I had to add the following in the nginx custom config:

location ~* \.(ico|jpg|jpeg|png|gif|svg|js|css|swf|eot|ttf|otf|woff|woff2|html|json)$ {
     add_header 'Cache-Control' 'public';
    add_header 'X-Frame-Options' 'ALLOW-FROM *';
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Credentials' 'true';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
    expires +1y;
}

After that, all my static assets successfully loaded on frontend.
Apparently on the admin panel(Magento 2), when using a CDN, there are OPTIONS requests made from a js file to load certain .html(pretty odd??)
When removing the CDN, the .html files load normally through a GET request as they do on the frontend.

My problem is that the OPTIONS request gives the following result(the request is made towards cdn.mydomain.com/static/tooltip.html ):

Also, when doing an OPTIONS request from Postman to mydomain.com/static/tooltip.html directly(without cdn), I get 'Could not get any response' from Postman.
When doing an OPTIONS request from Postman to mydomain.com:8081/static/tooltip.html, I get a 402 answer from apache telling me that method OPTIONS is not allowed.


Any ideas on fixing this? I don't get why is there an OPTIONS request made instead of a GET to load the .html file. I've been spending the whole day playing around with nginx and cors settings..

Thank you!

I've actually switched the backend port to apache(8080) as with 1424, I was getting 404 for different files. The issue is still there.
nginx(listens 443) -> proxies to Varnish(port 80) -> Varnish gets data from backend port 8080(apache).

When I decided to finally give up and change back to Litespeed, I saw under 'Webserver' at Custombuild (Edit Options) a input called
http_methods that only had

GET:HEAD:POST

, I made that to

GET:HEAD:POST:OPTIONS

did a ./build rewrite_confs and voila, it works .

Finally!~

BTW: Varnish isn't supported Natively.

nginx custom config

Hopefully, you set up all the nginx / apache templates up in the Custom directory.
Seems like you did.

Webserver' at Custombuild (Edit Options) a input called
http_methods

Yep, that is the Standard entry.

Glad you found it.
