Firefox will only preload 6 audio files

[kunikla]

When a file is downloaded using PHP functions, Firefox leaves the connections to the server open. There is a limit of 6 connections, so it stops preloading (or any kind of loading) after 6 files. The 7th call to fpassthru() or readfile() never returns, and the browser shows a status of "waiting for mydomain.com".

This does not appear to be a problem with Chrome. Still need to test IE and Safari.

Temporary solution is to allow calls to file_markup() and files_for_item() to specify preload="none" (or "metadata" or "auto", the other two valid values).

The Big Picture theme has been updated to specify preload="none". Protected audio files are not downloaded until the user clicks on the controls. The duration of the audio file therefore does not display until the file is downloaded.

A long-term solution is to allow the site administrator to configure the setting for preload. There may be sites with fewer than 6 protected files per Item that this limitation will not affect. This enhancement should be given highest priority.

User Documentation: Requirements has been updated.
