HTTP 102 Processing vs 426 Upgrade Required
HTTP 102 (Processing) is a 1xx Informational response, while 426 (Upgrade Required) is a 4xx Client 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, 426 means that the server refuses to perform the request using the current protocol but might after the client upgrades to a different protocol.
