[thelist] Cache control

[Peter-Paul Koch]

We all know the situations in which a page is cached that shouldn't be 
cached (an answer to a POST, for instance). I've just encountered one and 
provisionally solved it, but it set me wondering.

What I did was simply appending the time in milliseconds to the query string 
so that each request would have a unique URL.

My question is: is this a completely fail safe method of avoiding caching? 
(Assume JavaScript is always enabled).

Thanks for any insight,

ppk
