GWT/GXT adding nocache.js file, in the header or after the body?

I notice that most GXT/GWT applications put the nocache.js file after the body tag. And few seem to put in the include in the header tag. Why is that?

Solution

  • Given the fact that the GWT script tag will be evaluated synchronously (the tag), but fetched asynchronously (the code, into an iframe), I don't see why not put it as the very first thing. Time saved!

    Unless, you have some kind of complex logic that cannot have the chance to be properly displayed before the onModuleLoad() call (e.g., images evaluated but still not fetched), much like Steffen Schäfer pointed out. But you can defer you app startup for them though.
