problems with downloading a file

I have problems with downloading a file from any path. I’m trying to download it from other server using GET request.
When i got the response it says:
‘This site requires Javascript to work, please enable Javascript in your browser or use a browser with Javascript support’

and that appears also when the file doesn’t exists!

What means this code and how to access the original file?

it means you are hit aes.js (protection from infinityfree)
