hi dylan

i am fairly new to the web-worker spec
could you or anyone else on this list enumerate the advantages of web-worker implementation of
var server = new WebSocket('ws://whatwg.org/database');
server.onmessage = function (event) {
over classic http request/response to the same website?

> I have a question about Web Workers
> It seems like the spec http://www.whatwg.org/specs/web-workers/current-work/ 
>   is somewhat confused about whether any documents are available in  
> the GlobalWorkerScope.
> On the one hand, it says that if the script creating the Worker's  
> global object is a Window,  then the document should be added to the  
> "worker's Documents",but then goes on to say that the DOM API is not  
> available to the Worker in this version of the spec.
> How does adding the document to the WorkerGlobalScope help if the DOM  
> API is not available?
> Doesn't this really reduce the usefulness of the Worker object by  
> restricting it to tasks that have nothing to do with the DOM - e.g.  
> analyzing it as it changes?
> thoughts on this?
