Some resources on CORS proxies
Posted by jpluimers on 2023/04/19
Having my background before the web-development era, and having lived mostly in back-ends or client-server front-ends, I sometimes need to really dig into things in order to understand them better.
CORS is such a thing, so below are some links to get started. My main interest is CORS proxies as they will force me do go deep and really get what is going on below the surface.
- Cross-origin resource sharing – Wikipedia
Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.
- [Wayback/Archive] Cross-Origin Resource Sharing (CORS) introductory article describing the basics and the various headers/responses involved.
- [Wayback/Archive] enable cross-origin resource sharing in depth site including loads of documentation references and a test front-end:
