HTTP Status Codes

102 Processing

A WebDAV interim response indicating a lengthy request is still being processed, sent to stop the client from timing out.

What it means

102 Processing (RFC 2518, WebDAV) is an interim status a server can send while a method that may take a long time — such as a deep PROPFIND or MOVE on a large collection — is still running. It reassures the client that the request was received and work is ongoing. It has largely been deprecated in favour of 103 Early Hints for general use.

Why it matters

  • It keeps WebDAV clients from abandoning a request that legitimately takes many seconds.

Common mistakes

  • Using 102 on ordinary web APIs where clients do not understand it — it belongs to WebDAV.

How WebInspect checks this

  • WebInspect records the final response status and timing; interim 1xx frames are surfaced where the transport exposes them.
