ContentPane::setUrl() stores empty cache

[Stickman]

The following is based on an SVN checkout today, 17th Aug 06.

When using setUrl() to load external content in a ContentPane?, if you then try to reload the same content (with cacheContent set to true) the cache returns an empty string. This is applicable to Firefox 1.5.0.6 and MSIE 6 (but oddly, not Opera 9).

After some detective work I tracked it down...

The load callback for the _ioBindObj (in ContentPane::_downloadExternalContent()) calls ContentPane::onDownloadEnd(), which in turn calls ContentPane::setContent(). The first thing that setContent() does is call ContentPane::abort(), which calls _ioBindObj.abort(), which finally calls the abort() method of the XMLHTTPRequest object that was used to fetch the external file. In FF and IE, this causes the XMLHTTPRequest's responseText field to be blanked -- so while the object is cached, it no longer has its data.

Well anyway, that's what I think is going on...

I belive that this is no longer an issue with 0.9. 0.9 doesn't have a javascript cache anymore, as all new browser have built xhr cache.
