Web games that use the Unity game engine, such as https://apps.facebook.com/shopheroes/ are experiencing excessive load times in Chrome, mostly due to Script compilation.

I observed that upon reload, the code cache is not kicking in. It seems that the app is downloading the code in compressed form via XHR, then decompressing it into a blob, then the blob's URL is used to load it into a script tag.

What I think is happening is that because the blob is a brand new resource (unique URL every time),  the V8 code cache might not be recognizing it upon re-load.

1) Is this something we can fix with the code cache?
or
2) Is there a better way to implement script decompression + async loading that will play nice with the code cache.
