Caching prevention

[marekk]

Hi all ;)

I need some help with the following:

I have a JAVA applet on page, which I don't want to be cached by browser.
Is there any possibility how to tell the browser not to cache an applet (I mean a property of the <applet> tag, ets.) ?

The html page the applet is used on, does have following meta tags setting:
<META HTTP-EQUIV="Expires" CONTENT="0">
<META http-equiv="Pragma" content="no-cache">
<META http-equiv="Cache-Control" content="no-cache">

so the html file itself is not cached, but when I call:

<applet name='test' archive="../class/test.jar" ...>

the test.jar file is always cached.

Can anybody help me, how to prevent the caching of the .jar file ?

Thank you.

You cannot keep browsers from caching anything. You can ask but they won't always comply. For non-HTML files you need to adjust the HTTP header that your server pre-pends to the file. If you just want to avoid the possibility of browsers not downloading the newest version of your applet then send a really old date or set the date to '0'. And know that anything that you might want to put in an HTTP-EQUIV META element, you can put in the HTTP header.

Thank you ;)

Do you know how do I pre-pend a header to .jar file-type in Apache ? Is there a Apache module for it, ro do I have to programm one ?

I don't know how to that actually, but I do know that, above, I should have written 'Expires' where I wrote 'Date'.

I found the Apache Module. You can find the description at
