Btw, there is a simple test in this page, it load a movieclip from a php page that log how many request the server receive.
If it is green, then your client is asking for the movieclip only the first time, subsequent calls doesn’t produce an http request.

However, looking at the statistics of the test, sometimes it seems to fail, but I haven’t isolated the cause.

Try to use Charles debugger(google it), or even apple safari debugger and you`ll see the load calls.
I did a solution like yours some time ago to a project I was working, and it was very slow inside any browser(due the flash load a new file in every call).
After use shared library, it speed up 200% and stop the “HTTP1/1 304 Not Modified”.
The only shared library problem, I think, it the need to import the externals swf reference.

I think flash 9/10 can attach others swf assets without need shared object or a solution like yours.

Sniffing the traffic (http://www.wireshark.org/) I’ve see only a request per item.

It will try to load an url only once, then it will take the cached item at every load attempt.
Like a browser: IE, Firefox, ecc, will load an image only the first time it occurs in a page.

Ps: I’m referring to Flash 8, I don’t know if Flash 9 is different.

“Maybe because I have always thought that “loadClip” would have loaded file, maybe receiving a “HTTP1/1 304 Not Modified” reply, instead of silently take the cached one, who knows!
”
Well, acually it do receives a “HTTP1/1 304 Not Modified” everytime a load call is attemp.
flash cannot “silently take the cached one”.

Aynway, Thanks.

The main difference from attachMovie is that the attached movieclip will not be avaible until the next frame.

With attachMovie the item it’s attached and available in the frame where the code is scoped.
How can a movieclip be available in the next frame if it’s attached in the previous?

Thanks a lot

Your solution, although very simple, surprised me. I would have thought that if Flash cached files loaded by MovieClipLoader, then this code… (using the same MovieClipLoader “mcLoader” to load the same file onto the same target twice)….

var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.loadClip(“libraryfile.swf”, target);
mcLoader.loadClip(“libraryfile.swf”, target);

… would have worked in a similar way to the code that you provided (which uses a second MovieClipLoader “mcLoader2″ and a second target “target2″)…

var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.loadClip(“libraryfile.swf”, target);
var mcLoader2:MovieClipLoader = new MovieClipLoader();
mcLoader2.loadClip(“libraryfile.swf”, target2);

…but no! Using the same MovieClipLoader OR the same target on the second load clears the cache. I tested them all.

Now that I know how this works I am very happy. Thanks again for sharing.
