The [File_Stream] tag incrementally serves a file on the server in place of the current Lasso format file. This tag is simialr to [File_Serve], but does not read the entire file into memory before serving it. This allows it to serve large files efficiently.
The name of the file can be specified and, in supported browsers, the file will be written to disk using that name and/or displayed in the browser. The [File_Stream] tag can be used to serve image files, multimedia files, file archives, or even HTML files.
None of the contents of the current format file will be served. [File_Stream] completely rewrites the HTTP headers and contents of the served response. [File_Stream] also performs an [Abort] so no tags after [File_Stream] will be executed.
