}What is HTTP 226 IM Used?
HTTP 226 IM Used indicates that the server has fulfilled a GET request for the resource, and the response is a representation of the result of one or more instance-manipulations applied to the current instance. This is used with delta encoding.
- Delta Encoding: Response contains delta/diff from cached version
- Instance Manipulation: Applied transformations to the resource
- Bandwidth Optimization: Reduces data transfer by sending only changes
- IM Header: Uses Instance Manipulation (IM) header
When Does This Happen?
A 226 IM Used response is returned when the server sends a delta-encoded response instead of the full resource. You'll see this status code when:
- Using delta encoding to reduce bandwidth usage
- Sending only changes since a cached version
- Applying instance manipulations like compression or transformations
- Optimizing responses for clients with cached content
- Working with HTTP delta encoding implementations
