Allow CORS for all subdirectories
it flag

Hi,

I have this htaccess to allow CORS in my website but seems like it only applies to the root directory

Header always set Access-Control-Allow-Origin "*" Header set Access-Control-Allow-Headers "origin, x-requested-with, content-type" Header set Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS" how can I change it so it applies to subdirectories as well?

Thank you.

CORS and Nginx in front of apache reverse proxy/proxy pass not working to access API server
id flag

I'm trying to set up a reverse proxy to my api server but getting a 404 error page.

Context: Whilst setting up a react.js application and trying to find a solution to the CORS problem, I've decided to use reverse proxy (proxy pass) with nginx to invoke the api server internally and trick the browser to think the api is on the same domain.

This is my intended setup:

Tai

I have a website with a HTML form that, when submitted, successfully sends a POST request to a .php file on the server (Apache 2.4.48).

However, when I let Javascript handle the submitting through a JS fetch(), the server responds with a 405 error.

So I analysed the request and response headers for the two POST and they are almost identical, so I am confused on why the first method works and the oth ...
