Add headers to OPTIONS/HEAD methods for CORS headers

[samichoulo911]

I am currently having issues with some requests due to CORS. I was able to fix my GET/POST methods with the following headers

response.add_header("Access-Control-Allow-Origin", "*");
response.add_header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
response.add_header("Access-Control-Allow-Methods", "PUT, POST, GET, DELETE, OPTIONS");
response.add_header("Content-Type", "text/plain");

My issue is when I try to make PUT requests, since they make preflight OPTIONS request. I believe this issue (#117) catches all the OPTIONS/HEAD requests preventing me from adding my own handlers for my routes. Is there a way to configure global headers for all incoming requests? I was thinking of using midleware but I am not sure it is the way to go.

Hi, does this guide address your issue?

Yes! This is exactly what I was looking for, I was using an old version so I didn't have the CORS middleware thanks!

Hi @The-EDev - I'm having the same issue on the current version of CrowCpp, while using the CORs middleware. The browser sends a preflight OPTIONS request and gets back a 204 without CORs headers, and I'm not sure how to set it up to fix that. The guide you linked above no longer works, and the current guide does not explain this, and also has a broken link to the methods documentation. Do you have any suggestions on how I can get my app to reply to the OPTIONS request correctly?
