Force Get object to refresh content

I'm using Jamie's Get object in a Standalone Java Internet Applet. It works great but there's a problem: The Get object does not recognize if there's a change in the source file (refreshing the page does not work), so I have to restart the browser the see the changes.
Is there a way to force the Get object to reload the source page content?
Thanks. :)

I would assume it's caching it because your webserver is telling it that it can...

Thank you Dynasoft for your answer! I've found the problem: there's a cache folder on my Mac that stores temporary files for fast access. I have to delete the stored file.

Does the Standalone Java Internet Applet have access to the cache folder to delete the stored temporary files? Just because this problem can appear on Windows, too. There's the page that explains how to clear cache:
http://java.com/en/download/help/plugin_cache.xml

But I think it isn't very elegant way to tell the users that "Please clear the Java cache if you want to see the effect of your changes". There should be a solution for this. Any ideas?

Thanks. :)

I'll see if there's any way I can persuade Java to bypass the cache when I write the updated Get object's Java version.

Wow, that's very kind of you, Jamie! Thank you very much!

You should be able to configure your webserver to change the cache time of any file on it (or disable caching for your file).
If the file is dynamic (e.g. php) it should be set to not cache by default, but you can send headers back manually from PHP to control cache time.

Thanks, Dynasoft, but I think these files are stored in Java's own cache folder and users can disable caching in the Java preferences. So this cache is not the same as the browser's cache.

They are still retrieved by HTTP Get, and so should still be obeying the same caching rules.

Oh, I understand now!
To be honest, this application will run on other servers too. So I'm not sure that all of my customers will be able to change their server rules.
We'll see what Jamie can do with the Get object. :)

Thanks!

What kind of file is it? A dynamic file (php) can alter its own caching rules, a static file (html, png, zip, etc) can have its caching settings changed by either server configuration or a .htaccess file (on most webservers).

It's a txt file. Do you know what I should write into the htaccess file?

You could add a cache buster - get

"myTextFile.txt?cacheBuster=" + random(999999)

(ideally the random(999999) would be the current time, but whatever).

Using random is a horrible idea. Also, this method will probably end up with the client caching a new copy of the same file every request (instead of not caching it at all).

Jamie, your idea might be dirty, but it works very well. Also, it does not make a new file for every new query. (I've used the actual time instead of the random number, though. :D )
