Hi, 
I am a beginner in CL-HTTP.
I have run above code on ACL and netscape3.0b7.

If I push 'Submit' button, the response-function prints out the selected file
and also  prints odd string like '------15080299524862561851062517886--'.
and then waits without end.
Do I have any mistake?
Please give me a help.

and  If you have any Example about upload/download file in CL-HTTP,
please give me some Example !!!

Thanks.
