Prevent Player Cache Issues
Posted: Fri Jan 13, 2012 6:19 pmI know this is in a million other posts, so I started a new topic. I developed a method of preventing the common browser cache issues that cause the player to appear to begin loading, but stops the music within the first few seconds of playback.
After this modification, you will rarely if ever have to clear your cache to play a song.
Basically, we are going to salt the URL passed to the player in playlist.jsp.
Because the cache stores separate info for each unique URL, this will prevent the cache from re-caching the same URL over and over, which is what causes the problem in the first place.
We are going to edit playlist.jsp.
Here is the part of the file we are going to edit:
All you have to do, is replace it with this:
That will append a parameter named "salt" to the end of the URL and the value of the parameter will be picked randomly.
Hope this helps!

- Code: Select all
function skip(index) {
if (index < 0 || index >= songs.length) {
return;
}
var song = songs[index];
currentStreamUrl = song.streamUrl;
updateCurrentImage();
var list = new Array();
list[0] = {
file:song.streamUrl,
title:song.title,
provider:"sound"
};
if (song.duration != null) {
list[0].duration = song.duration;
}
if (song.format == "aac" || song.format == "m4a") {
list[0].provider = "video";
}
player.sendEvent("LOAD", list);
player.sendEvent("PLAY");
}

var saltedUrl = song.streamUrl + "&salt=" + Math.floor(Math.random()*100000);
currentStreamUrl = song.streamUrl;
updateCurrentImage();

list[0] = {
file:saltedUrl,
