Indicating Already Reported ResourcesHTTP Status Code | ||
208 Already Reported Overview 208 Already Reported is an HTTP status code used in the WebDAV protocol to indicate that a resource has already been reported within the response. This prevents the same resource from being listed multiple times, reducing redundancy in the response. |
||
Meaning The client’s request was successful. Since the same resource has already been reported, it will not be listed again in the response. |
When is 208 Already Reported Returned?
- When performing a deep resource search using the WebDAV
PROPFIND
method - When the same resource could be discovered through multiple references
- When avoiding duplicate resource reporting is necessary to create efficient responses
Examples of 208 Already Reported
Preventing Resource Duplication in WebDAV
PROPFIND /collection/ HTTP/1.1 Host: example.com Depth: infinity
Response example:
HTTP/1.1 207 Multi-Status Content-Type: application/xml; charset=UTF-8 <?xml version="1.0" encoding="UTF-8"?> <multistatus xmlns="DAV:"> <response> <href>/collection/resource1</href> <status>HTTP/1.1 200 OK</status> </response> <response> <href>/collection/subcollection/resource1</href> <status>HTTP/1.1 208 Already Reported</status> </response> </multistatus>
Explanation: When a client recursively searches a collection and the same resource is referenced from multiple locations, the 208 status code is used after the initial report to suppress duplicate resource information.
Points to Note
Considerations when returning 208 Already Reported:
- Avoid duplication in responses
Using the 208 status code improves response efficiency while ensuring that critical information is not omitted. - Ensure consistent response formatting
WebDAV responses typically use XML format, and properly formatted responses must be returned.
