Let us learn how to setup plesk allow cors. With the support of our Plesk hosting support services at Bobcares we will learn more about CORS and how to set it up with Plesk.

What is CORS in Plesk?

“Cross-Origin Resource Sharing,” or “CORS,” is a security mechanism added by web browsers to prevent malicious scripts from accessing resources from a different origin.

In the context of Plesk, “allowing CORS” involves explicitly permitting cross origin requests from certain domains or all domains.

This is usually done by appending particular headers to the server’s response, such as “Access Control Allow Origin,” “Access-Control-Allow-Headers,” and “Access-Control-Allow-Methods.”

Web developers may enable CORS to allow their web applications to access resources from various domains. This is frequently required when leveraging APIs or external resources from third party websites.

How to setup CORS in Plesk?

CORS is available in the following browsers. Make sure to go through this before allowing CORS in Plesk:

Chrome 3 and up, Firefox 3.5 and up, Opera 12 and up, Safari 4 and up, and Internet Explorer 8 and up.

We can add only one Access-Control-Allow-Origin header. CORS will not work if the header is declared twice in nginx and Apache, or once in Apache and once in nginx.

• Log in to Plesk on the server that hosts the domain example.com.
• Go to Domains > example.com > Apache & nginx Configuration.
• Add the CORS header:
• For Apche insert the following line into the Additional HTTP Directives field:

  
• Similarly for Nginx Depending on whether the website uses HTTP or HTTPS, add one of the following lines to the Additional nginx directives field:

  
• Finally, click on the OK or the Apply button to apply the changes and this will plesk allow cors.
