Downloading mystery

[Bruce A. Pokras]

I am trying to script the downloading of European patents from the 
European Patent Office's server. They provide a sample URL to use for 
that purpose, but instead of the patent, I instantly get a zero size 
file. I've tried it with and without URLencode. However, scriptiing 
with revGoURL works fine with the same URL to open the patent in my 
browser. Any ideas? The script I am using goes like this:

on mouseup
put 
"https://publications.european-patent-office.org/PublicationServer/getpdf.jsp?cc=EP&pn=1502503&ki=A1" 
into theURL
    
put URL theURL into URL "binfile:1502503.pdf"
end mouseup

Could it be that Rev is allergic to JavaServer Pages? I hope not. 
Thanks for any help that you might be able to give.

Regards,
