As I understand it the <base> element is used to specify the URL of the
document it occurs in. This allows it's "real" location to be found when
the document is read out of context. Any partial URLs are read within
the document are read relative to this URL.

That is not a full URL. It should be something like:

<base href="http://www.blah.blah/">

The above should work if you specify the base URL fully.

I imagine this is because the "#section" is a partial URL which is
always relative to the URL of the current document. You have redefined
it as "www.blah.blah" so it's trying to find the document in that.

Hope this is clear.

I find

an invaluable starting point.
