Behavior name: Large File Optimization (Advanced)

The Large File Optimization feature improves performance and reliability when delivering large files. You need this behavior for objects larger than 1.8GB, and it's recommended for anything over 100MB. You should apply it only to the specific content to be optimized, such as a download directory's .gz files. Note that it is best to use NetStorage for objects larger than 1.8GB.

This advanced behavior provides additional HTTP/2 options not present in the large_file_optimization behavior.
