As of today (Jan 21), Google Drive has a problem in servicing public javascript 
files. 

I have created a test public javascipt file: 

https://drive.google.com/file/d/0B0LhXyqXqQSpNkVScGVtQ2thY3M/view 

Normally, you can download it from: 

https://googledrive.com/host/0B0LhXyqXqQSpNkVScGVtQ2thY3M 

which redirects to: 

https://d18bae7de9be5a4af7a66421e9e82cc342d129e1.googledrive.com/host/0B0LhXyqXq
QSpNkVScGVtQ2thY3M 

which, today, shows an error page with code: ERR_SPDY_PROTOCOL_ERROR 

Now open developer tools, refresh, and right click on the failed GET request. 
Select "Copy as cURL" and execute the curl command (use Cygwin on Windows): 

curl 
"https://d18bae7de9be5a4af7a66421e9e82cc342d129e1.googledrive.com/host/0B0LhXyqX
qQSpNkVScGVtQ2thY3M" -H "Accept: 
text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H 
"Referer: " -H "User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) 
AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.99 Safari/537.36" 
--compressed 

The response is "curl: (52) Empty reply from server" 

If you remove the --compressed flag, which essentially sends the 
"Accept-Encoding: deflate, gzip" HTTP header, everything works great and you 
get: 

console.log('hi'); 

which is the content of the test javascript file. 

Html files work normally even with compression enabled and actually applied on 
the content. I think that something changed on the HTTP servers today and broke 
things up. Seems like gzip does not work properly. The problem is that I cannot 
convince the browser to request the file without adding the header (I use a 
script tag on an html page).
