A single linker would be able to provide cross-domain-capable, multi-module-safe code that doesn't require any additional post-processing to support loading of fragments. It also runs in the global scope, saving the extra few ms per global access (<a rel="nofollow" href="http://blog.j15r.com/2009/08/where-should-i-define-javascript.html">http://blog.j15r.com/2009/08/where-should-i-define-javascript.html</a> ).</pre><pre> The method used to load the first and additional fragments could become a linker property. For our cross-domain loads, I'd like to have a strategy that tries to use cross-domain XMLHttpRequest first, assuming appropriate Access-Control-* headers on the other end, then falls back to <script> tags if this isn't available. The default could be something simple like <script> tags, or even standard XMLHttpRequest, assuming the auxiliary scripts are stored on the same domain. It still has the disadvantage of being slightly more magical, requiring tricks to work around IE's window event security, but the advantages are pretty substantial. It should be possible to write this linker as a drop-in replacement for today's XSLinker and IFrameLinkers without touching any code outside of com.google.gwt.core.linker. Matt.
