Okay, I think I finally see what the problem is.
The complete syntax for a <meta> direct is this:
https://developer.mozilla.org/en/HTML/Element/meta#attr-http-equiv
In the "refresh" bit we can read:
«This pragma specifies:
- the number of seconds until the page should be reloaded, if the
content attribute contains only a positive integer number;
- the number of seconds until the page should be redirected to another,
if the content attribute contains a positive integer number followed by
the string ';url=' and a valid URL.»
I guess you are using the first feature ("reload") and I thought you
were using the second one ("redirect"). Just tweak your PHP code to
generate a <meta> tag with the ";url=" part.
