The problem is in mod_python. When i use "req.sendfile()" my "req.headers_out" probably are rewrited by Apache. Is any way to use "req.sendfile()" with resume? Where i must search? Using "req.write()" for lage files is very bad. Can i use successive "req.write(); req.flush()" with small pieces of lage file? -- Best regards, Enot mailto:enotus at tut.by
