on the threshold of a dream
Actually even on AOL you can set your own cache settings. Not really an AOL issue as much as just a preference setting.
The following is for AOL 4.0 (don't remember in's and out's of 3.0):
To find the area you need to change go MyAOL >> Preferences >> WWW >> on the first tab, you want temporary internet files area, click settings there. Presto... tell your browser how often to check for new version of a web page.
You can do this in AOL 3.0, just find the preferences area and all is the same.
Hope that helps.
