HTTP 102 Processing vs 504 Gateway Timeout
HTTP 102 (Processing) is a 1xx Informational response, while 504 (Gateway Timeout) is a 5xx Server Error response. 102 indicates that the server has received and is processing the request, but no response is available yet. Prevents the client from timing out. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.

When You See It
During long-running WebDAV operations.

Wait for the final response. This is an interim status to prevent timeouts.
Description
The server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
When You See It
When an upstream server is too slow to respond within the proxy's timeout window.
How to Fix
Increase proxy timeout settings. Optimize upstream server performance. Check for long-running queries.
Key Differences
