Sending file with Servlet, Problem if filename contains whitespaces

I'm sending files by a
. I'm setting the filename by using
res.setHeader("Content-Disposition", "attachment; filename=" + filename);
This works fine. But if the filename contains whitespaces, my Firefox cuts the filename before the whitespace. So all chars behind the whitespace (including the extension!) get lost. Are there any solutions for this?

Did you try with double-quotations too ?

What I would try is this:
Create an empty directory on your webserver (call it junk).
Put a file with spaces in the name ("space in name.html")
Point your browser at that directory.
Click on the link for that file.
Using the LiveHTTPHeaders plugin for FireFox, view the filename as it's being sent.
This will be the default way of packaging files with spaces in the name over HTTP.
I did this and saw:
[B]GET /junk/space%20in%20name.html HTTP/1.1[/B] Host: <a href="http://www.souther.us" target="_blank" rel="nofollow">www.souther.us</a> User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5
This shows me that servers handle spaces in th names by URL Encoding them and that browsers expect this and already know how to deal with it.
