My example was showing literally what the browser would receive, not the order in which the program was generating output. I am effectively doing the same thing wrt to buffering in PHP3 by creating the entire page and then sending any desired headers followed by the page once I know exactly what will need to be sent (i.e., errors have been handled or whatever). My understanding of what Michael Stearne was saying in: Either way is easy to use, but there is sometimes an advantage in running some output before the page is redirected. I know this can be done with a <META> tag, but I don't like the fact that the user can hit Stop on the browser. was that in this case the browser was receiving some HTML and then receiving an HTTP redirect. As far as I know, that isn't standard. I was suggesting that an approach is to do what I am doing because then you can make whatever decisions you need to before starting to talk to the browser. -- Peter.
