COREDNS-CANCEL(7) CoreDNS Plugins COREDNS-CANCEL(7) NAME cancel - cancels a request's context after 5001 milliseconds. DESCRIPTION The cancel plugin creates a canceling context for each request. It adds a timeout that gets triggered after 5001 milliseconds. The 5001 number was chosen because the default timeout for DNS clients is 5 seconds, after that they give up. A plugin interested in the cancellation status should call plugin.Done() on the context. If the context was canceled due to a timeout the plugin should not write anything back to the client and return a value indicating CoreDNS should not either; a zero return value should suffice for that. SYNTAX cancel [TIMEOUT] * TIMEOUT allows setting a custom timeout. The default timeout is 5001 milliseconds (5001 ms) EXAMPLES example.org { cancel whoami } Or with a custom timeout: example.org { cancel 1s whoami } SEE ALSO The Go documentation for the context package.
