Now http://faculty.sfasu.edu/judsontw/math-s304/section-16.html works fine for me - I don't enforce permission on user files except for group readable (otherwise the web server will not be able to serve them) and there is a timestamp added to the name to force browser to load a new version.
The next problem is that if a linked cell does not create a new plot, then the old one will be shown again - since the file is still there. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
