I find that IE often ignores such “cachebusting” strategies as putting random variables in the query string. Anyone have a workaround?

It’s noteworthy that after all these years the idiots at Adobe still haven’t been able to set up a properly working cache system. It doesn’t even work consistently stupidly – sometimes it will load the new file (swf or xml or whatever) and sometimes it won’t. So it’s doubly stupid.

I just use nocache by default and a GUID class i found on line:

var nocacheKey:String = “?nocache=” + GUID.create();

var urlLoader……
urlLoader.load(fileToLoad+nocacheKey);

Here is a trick I learned years ago for AS2 and just tested in AS3. It works great.

Mind you it doesn’t work offline but all you do is add the code before you go live.

Change this –> l.load(new URLRequest(“your_file.swf”));
To this –> l.load(new URLRequest(“your_file.swf?ver=” + Math.floor(Math.random() * 999)));

With this code it never loads from the cache unless by some magical chance the random number is the same as the cache version

shine,
Yes, in my example above I describe the process of embedding a “shell” swf in the HTML and passing that swf file a variable of the “app” location. Personally I use swfObject to embed the shell swf file. It’s painless and easy to pass in variables.

For more information about embedding using swfObject, go here:

Hi,
Can you please put a sample file for this or please explain step by step. Do you mean loading a swf file from the embedded swf in html?

Oh yeah, these project launches are usually pain in the a$$. I decided not to name the files filename_1, filename_2, filename_3 etc. but to copy the whole system to a new folder folder-1/, folder-2/, folder-3/ etc. It allows also to roll back if the client doesn’t want something from the new version.
