HTTP 102 Processing is a WebDAV status code indicating that the server has received and is processing the request, but no response is available yet. This prevents the client from timing out while the server works on a long-running operation.

<server is preparing the large file — final response will follow>How to Troubleshoot
Wait for the final response
102 Processing is informational — the server will send a final response when the operation completes.
Increase client timeout
If the client disconnects prematurely, increase the request timeout to accommodate long operations.
Check server logs
If the operation never completes, check server logs for errors or resource exhaustion.
Common Causes
Long-running WebDAV operation
highA COPY, MOVE, or PROPFIND operation on a large collection of resources takes time to complete.
