I have a file download 'guardian' page which does something like this:
$size = filesize($path);
$fi = @finfo_file($path, FILEINFO_MIME_TYPE);
@header('Content-type: ' . $fi);
@header('Content-Length: ' . $size);
@readfile($path);
exit;
($path is derived from parameters in the request, including checks for nasties
and some access control checks in the system)
When a link is clicked which points to this script, the file is downloaded (well
and good...), but in Firefox (3.x, 4.x at least), it seems to block any further
interaction with the browser until the download is complete - some of the files
are 60Gb and the server is on a 2mbit line, so it can take some time to download.
Is there something on the Apache/PHP end that might be causing this blocking?
(Apache 2.2.10, PHP 5.2.14)
I suspect not, since using Chrome as the browser doesn't appear to have the same
problem, but I wondered whether there was some way that FF was handling the
headers might be causing it.
I can't seem to devise a suitable Google search to get any mention of similar
behaviour so I thought I'd ask some experts :)
