Domain fronting works by taking advantage of the way network connections are established. When a client makes a request to a domain, it first communicates with the front domain, which acts as a proxy, forwarding the connection to the desired destination. This technique makes it difficult for censors to identify and block specific applications or services, as the actual target is concealed behind a legitimate domain name.

However, domain fronting has limitations and controversies. Some hosting providers and content delivery networks (CDNs) have disabled domain fronting, making it challenging to implement.

Despite its endurance as a circumvention technique, domain fronting is often viewed with skepticism due to its potential misuse. It operates by utilizing legitimate domain names to hide the actual target, making it challenging for censors to identify and block specific applications or services.
