To configure CORS in Apache, you need to add the necessary headers to your Apache configuration file.

For CentOS/RHEL-based systems: sudo yum install httpd-develĪfter installing and enabling the headers module, restart the Apache service: sudo service apache2 restart Step 2: Configure CORS in Apache.For Ubuntu/Debian-based systems: sudo apt-get install libapache2-mod-headers sudo a2enmod headers.If it is not already installed and enabled, you can do so by running the following commands: To enable CORS in Apache, you need to use the Apache headers module. Step 1: Install and Enable the Apache Headers Module In this article, we will guide you through enabling CORS in Apache, a widely-used web server, to allow cross-origin requests for your web applications. However, sometimes it is necessary to allow cross-origin requests for web applications to function correctly. By default, web browsers enforce the same-origin policy, which prevents web pages from making requests to a different domain than the one that served the web page. To allow cross-origin requests, add the frontend origin to the Access-Control-Allow-Origin header.Cross-Origin Resource Sharing (CORS) is an essential security feature for modern web applications, allowing web browsers to request resources from different domains securely. You can also restrict requests to certain IP addresses or block certain IP addresses if needed.

Apps that mimic a server environment and don’t enforce CORS, such as Postman or non-browser HTTP clients such as curl, are not affected by CORS so they bypass CORS restrictions.Ī server can protect resources by using an HTTP Authorization request header. It is not a strong security measure: It only restricts access, it does not protect your content. It can only block a frontend app from accessing cross-origin resources. CORS is implemented by browsers on the client side. CORS does not protect a resource, such as an API endpoint, against unwanted access. Why does requesting a cross-origin resource using Postman work? Postman does not enforce CORS. The most important of these headers is Access-Control-Allow-Origin, which specifies the origins that are allowed to access the resources from the server. The browser will allow certain cross-origin responses based on these extra headers. These headers start with Access-Control.

To allow cross-origin requests to be made, some changes need to be made to the server-side code to add extra headers to the HTTP response sent back to the browser client.

When a request is made, the browser client adds an Origin header to the request to indicate where the request came from.

CORS uses HTTP headers to indicate the origins that a browser should allow resources to be loaded from. To allow resource sharing between a server and a resource at a different origin, the browser uses a mechanism called cross-origin resource sharing (CORS). For example, it prevents malicious JavaScript on an attacker’s website from reading data and interacting with an embedded website in an iFrame that loads a website that the user may be logged in to. It prevents resources, such as API endpoints exposed by a server, from being accessible to a frontend website hosted at a different origin, such as another server. Why does this error happen? The same-origin policy is a browser security measure that restricts resource fetching from different origins. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. Access to fetch at ' from origin '' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
