Topic: Idea for solving the problem of cache
I like your simple viewer very much.
But the browser cache sucks.
I have an idea about how to solve it.
When the viewer request the xml file, just add a random number after the url to request.
The 134875509134 is a random number between 0 and 1.
It means the request url is not unique to the cache url, but the same.
Hope it's useful!
And if you have solved the cache problem, let me know, I can download a latest version.
