Hello

I have a media streaming URL with the following php codes at the end:

=====================
.
.
.
header("Content-type: audio/mpeg");

header(Content-Length: .filesize($rlu)); // provide file size

header("Expires: -1");

header("Cache-Manage: no-store, no-cache, must-revalidate");

header("Cache-Manage: post-check=0, pre-check=0", false);

readfile($rlu);
.
.
.
=====================

If i remove the lines:

header("Cache-Manage...

Is it enough to tell all browsers to cache my media data?

Thanks in advance :)
