HTTP 100 Continue vs 102 Processing

Both HTTP 100 (Continue) and 102 (Processing) belong to the 1xx Informational category. 100 indicates that the server has received the request headers and the client should proceed to send the request body. This lets the client know it can continue with the request or abort if the headers were rejected. Meanwhile, 102 means that the server has received and is processing the request, but no response is available yet. Prevents the client from timing out.
