URILoader.OpenURI(Channel,false,this);
http://lxr.mozilla.org/mozilla/source/uriloader/base/nsURILoader.cpp
nsCOMPtr loader =
new nsDocumentOpenInfo(aWindowContext, aIsContentPreferred, this);
loader->Open(channel);
aChannel->AsyncOpen(this, nsnull);
結局AsyncOpenで同じorz
nsCOMPtr
postDataSeekable(do_QueryInterface(aPostData));
if (postDataSeekable) {
rv = postDataSeekable->Seek(nsISeekableStream::NS_SEEK_SET, 0);
}
って事でSeekをsetすればいいのかな?
