Subj : How do we get notified of an AsyncRead()

Hi,

  I have implemented some code which embeds gecko. This code just
instantiates a nsWebBrowser and tries to LoadURI(). 

    For this I have implemented a few interfaces like the
nsIWebBrowserChrome, nsIEmbeddingSiteWindow,
nsIWebProgressListener,nsIWidget etc. It is compiled and it seems to run.
But its not loading the document when I call nsWebBrowser::LoadURI(). No
errors are returned.

    As I was stepping through the code, I found out that the
nsWebBrowser::LoadURI() calls nsDocShell::LoadURI(). This calls an
AsyncRead() and passes the request param to it and the code returns. This
obviously means that the read is happening in the background.

    I would like to know how we get notified when the data is ready in the
stream i.e the background read is complete.
Is there any call-backs/event handlers we should register anywhere? If yes,
please point out the place where we can register call-backs.

Thanks in advance,
Shreekanth
