HTTP 102 Processing vs 304 Not Modified
HTTP 102 (Processing) is a 1xx Informational response, while 304 (Not Modified) is a 3xx Redirection 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, 304 means that the resource has not been modified since the last request. The client can use its cached copy.
