Cache making posting complicating?

With the help of many of you, i have just made a very simple forum, using Perl to post to a text file. Then this file is loaded in a scroller.

But (here comes the problem…)…

A simple button to reload the text does not work because, text file is already in the navegator’s cache (or something like that). Even reloading the entire swf, the text with no-variations appears. When i clean the cache an reload, the new posts made are visible.

Is there a way to make the text file, or the entire swf movie ‘un-cacheable’?


maybe this helps
