This has nothing to do with the header function, but people seem to have big concerns about how to prevent pages from being cached. Another solution than the ones proposed is to add a random variable to the URI so that it's always unique. This involves neither header information nor <META> tags. Every time you print a link, do something like: $nocache=md5(uniqid(time()); print("<a href=\"http://my.site.com/dynamic.php?nocache=$nocache\">My Dynamic Page</a>"); You could even make the variable NAME random! If you have a stock procedure for generating links which also keeps track of query information, than it shouldn't be too hard to alter it this way.
