X-Clacks-Overhead is a non-standard HTTP header inspired by Terry Pratchett's Discworld series, specifically the Clacks semaphore network. It allows web servers to include tribute messages in their responses, ensuring the memory of individuals is perpetuated across the internet. This header is typically invisible to users but can be detected by analyzing HTTP headers. Notable organizations like Mozilla and Debian have adopted this practice to honor Sir Terry Pratchett.
