What is HTTP 102 Processing?
The 102 Processing status code is an informational HTTP response indicating that the server has accepted the request but has not completed processing it yet.
It is part of the 1xx Informational response family and was introduced for WebDAV operations that may take significant time to complete.
Why Does 102 Processing Exist?
Some operations require more time than a typical HTTP request.
Without an intermediate response, clients may assume the connection has failed and terminate the request.
The 102 Processing response tells the client:
The request is still being worked on.
Please wait.Example

Where Is It Used?
- WebDAV operations
- Large file processing
- Long-running backend tasks
- Complex server operations
Why Does It Matter For DevOps?
Although rarely seen in modern application logs, understanding 102 Processing helps when debugging long-running requests and asynchronous workflows.
- Timeout troubleshooting
- Reverse proxy configuration
- Long-running API requests
- Background processing systems
Summary
The 102 Processing response keeps clients informed that a request is still being handled.
