Solutions for Resolving CORS Errors
What are some possible solutions for CORS errors?
Possible solutions for CORS errors include modifying the external server to return the 'Access-Control-Allow-Origin' header, using a back-end proxy server, or embedding the resource directly into the web app. However, these solutions may not always be applicable, as some resources are not meant to be shared.
