Why does Traffic Layer always use cache?

Question

I made an app that shows Google maps with the Traffic Layer. The problem I have is that it always shows the traffic layer in the cache, so it is completely useless. I need the cache for other stuff.

How can I prevent the Traffic Layer from using the cache without completely disabling it from the app?

what type of app did you made? Android, IOS, native or hybrid? what type of cache do you mean also? — albanx, Jan 07 '15 at 11:38

@albanx The tags mention the javascript API. What he means by cache is that he is unable to force-refresh the traffic layer so that newer information is available. — MrUpsidown, Jan 12 '15 at 09:24
@Youssef this is not code-related. It is an issue with the API not providing a way to prevent caching of the data. — MrUpsidown, Jan 12 '15 at 09:24
@LuisA.Florit I suggest that you open a new [feature request](https://code.google.com/p/gmaps-api-issues/issues/list?can=2&q=apitype:Javascript3) as this doesn't seem to be possible. — MrUpsidown, Jan 12 '15 at 09:26
Good suggestion @MrUpsidown! I'm going to live with Sergio's dirty hack for now. — RichardTheKiwi, Jan 13 '15 at 03:36

As i already answered here, there seem to be no legal way to update traffic layer, even maps.google.com page don't autoupdate it. But i've found dirty hack that makes thing work - updating tile images manually:

function reloadTiles() {
    var tiles = $("#map-canvas").find("img");
    for (var i = 0; i < tiles.length; i++) {
        var src = $(tiles[i]).attr("src");
        if (/googleapis.com\/vt\?pb=/.test(src)) {              
            var new_src = src.split("&ts")[0] + '&ts=' + (new Date()).getTime();
            $(tiles[i]).attr("src", new_src);                                                   
        }               
    }
}
