101101 Switching Protocols
The server is switching protocols as requested by the client via an Upgrade header.
414The request URL is longer than the server is willing to interpret.
The URL exceeds the server's maximum URL length limit (typically 2048-8192 characters). This often happens when query parameters are too long, such as passing large data as URL parameters or deeply nested filter queries.
Move large data from query parameters to the request body using POST instead of GET. Shorten query parameters, use pagination, or encode parameters more efficiently.
101The server is switching protocols as requested by the client via an Upgrade header.
508The server detected an infinite loop while processing the request (WebDAV).
304The resource has not been modified since the last request, so the client can use its cached copy.
410The resource is no longer available and has been permanently removed. Unlike 404, this indicates intentional removal.
404The server cannot find the requested resource. The URL may be incorrect or the resource may have been deleted.
307The request should be repeated with the same method at the URL in the Location header. Unlike 302, the request method must not change.
