It shows either Startat=1 or >Startat=21. Is that not adequate as a unique value?No, that is not enough. Startat=1 and Startat=21 will come up time and time again when you perform the same search, and they probably already have come up repeatedly during your testing -- which is probably why you're seeing this problem. To fix it, just put something like:&u=[random][random][random][random][random]... into every URL in your site (just like you probably put &cart=[cart] into every URL) and it will prevent all browsers from reloading cached pages in your web site -- forever. >It could be AOHell's notorious server cache. I need to look into that more.It may be, since you're pretty sure it's not bad HTML. But placing a unique value in every URL will deal effectively with the AOL proxy server issues as well as the browser caching issue. From my understanding -- and in the absence of any reports to the contrary -- I have concluded that not even the most stupid browser or proxy server in the world will try to load or serve a page from its cache unless the entire URL looks *exactly* like one that's already been served. So all you really have to do is make every unique -- truly unique -- and you eliminate all caching problems ... which also means you never have to worry about using [setmimeheader] tags.
