The HiddenStor directive enables two-step file uploads: files are uploaded as ".in.filename." and once the upload is complete, renamed to just "filename". This provides a degree of atomicity and helps prevent 1) incomplete uploads and 2) files being used while they're still in the progress of being uploaded. Note: if the temporary file name is already in use (e.g., a server crash during upload), it will prevent the file from being uploaded.
The REST (Restart STOR) command is automatically blocked when HiddenStor is enabled, with the server returning a 501 error code to the client.
