Force xhrFetcher MIME type to 'text/html'

[GoogleCodeExporter]

On the production (Google App Engine) server, when fetiching a kml file, 
xhrFetcher.responseXML was null (on a perfectly fine XML response).
I've looked at the response and the MIME type was set to octect-stream.
So I forced it to 'text/xml' and the problem went away:

    xhrFetcher.overrideMimeType('text/xml');
    xhrFetcher.open('GET', url, true);
    ...

Does your fix work in IE?

I've looked at your link and the problem seems to affect only IE7.
I'm having other problems with IE8 and 9 that prevent me from checking whether 
my fix works.
It reminds me I should be trying with IE more often...

looks like you might be using an obsolete version of the code. That piece looks 
like this in the polys branch:
  xhrFetcher.fetcher.open('GET', url, true);

I've noticed the poly branch is significantly different from trunk.
There I see you parse the text response, rather than using the xml one.
I'll use the poly branch from now on. Thx!

in revision 56 the problem have not been solved:

xhrFetcher.fetcher.open('GET', url, true);

xhrFetcher.fetcher.send(null);

Please use the polys branch, not the trunk.
