102 Processing

A WebDAV interim response telling the client the server has accepted the request and is still working on it.

What it means

HTTP 102 Processing was defined for WebDAV to keep a connection alive during a request that takes a long time to complete. The server sends it to say the request was received and is being worked on, so the client should not assume the connection died and time out. It is not a final response, and the spec that defined it has since been deprecated.

When it happens

It shows up with WebDAV operations that touch many resources at once, such as a large COPY or MOVE across a collection, where the server needs time before it can return a real answer. Ordinary websites never send it.

How to fix it

  • Nothing to fix — 102 is an interim signal, not an error.
  • If a WebDAV client times out anyway, raise its read timeout so it waits for the final response.
  • Because the status is deprecated, prefer not to rely on it in new code.

SEO impact

None. It is a WebDAV-only interim response that search engines never encounter on indexable pages.
