First thing, do you want the visitor to receive the file as-is (gz encoded) ? Or should it be decoded automatically to text ?
In the first case, the browser shouldn't be aware of the encoding type (Content-Encoding header). You should only send 1 Content-Type header. The Content-Disposition header is nothing but trouble, and this is mainly caused by MSIE 5.5 . Microsoft managed to supply an update that changes the behaviour of MSIE 5.5 regarding this while the version still is 5.5 .. So there's no way to tell what header to sent for it to work properly. You could also expiriment with the extra keywords 'inline' and 'attachment'. header( 'Content-Disposition: attachment; filename=text.gz' ); But as I said, since browser behaviour varies on this header (even within same browser type/version) it's not easy to implement correctly for all browsers. I'm also not sure wether this header made it to the HTTP1.1 specs, but if you still want to use it I recommend consulting the website of W3C (http://www.w3c.org/), they should at least have some notes about it. bvr.
