one of the documented procedures in this installation of the ACS
What it does:
often netscape caches something we don't want to be cached. pragma: no-cache directive doesn't work always with netscape, either. solution is to pass a variable to a file, which will have a distinct value each time function is called. this function will pass a unix's time in seconds (pretty much guaranteed to be unique) in the variable called no_cache. usage of this function should be something like this
[util_kill_cache_form] form stuff
