102
Processing
Description
The 102 Processing status code is an interim response used to inform the client that the server has accepted the complete request but has not yet completed it. This status code should only be sent when the server has a reasonable expectation that the request will take significant time to complete. As guidance, if a method is taking longer than 20 seconds (a reasonable but arbitrary value) to process, the server should return a 102 response. The server must send a final response after the request has been completed. This status code was introduced by WebDAV (RFC 2518) and is primarily used in that context.
When Is It Used?
Used in WebDAV operations where a request may involve multiple sub-operations that take time. For example, a COPY or MOVE operation on a large directory tree might take a while, and 102 keeps the client from timing out.
