Browser caching problem? 1

[carmenMiranda]

I have a dynamic text area which loads it's content from an external text file using LoadVars(). When I upload a new text file, some users don't see the new text until they manually clear their browser cache.

This obviously isn't ideal and rather defeats the object of updating the text file on a daily basis. If this is indeed a browser caching problem, is there any way I can force the browser to display the new text (maybe triggering a cache-clearance) using actionscript?

You can append a unique number to your LoadVars(), that should force the browser to check the server for the file rather than using the cached one...

Something like...

// set up the unique number from date...
d = new Date();
// always a unique number
kill = d.getTime();

// Then when loading the text file...
loadVariablesNum("nocache.txt?kill="+kill, 0);

// Or...

loadVarsText = new LoadVars();
loadVarsText.load("nocache.txt?kill="+kill);
...

You can't really test this locally, text file must be uploaded to the server, and tested online.
