Would this allow users to start more than 2 downloads without waiting
for previous downloads to finish without causing excessive-connection
problems?:

When the user requests to download a document, if 2 connections are
already open (still downloading other documents), use a (short-term)
third connection to perform a HEAD request to get content type,
disposition and name information needed for the UI actions to start
the download, but queue the actual downloading until one of the two
long-term connections is free.

That way, the user could initiate multiple downloads right away
instead of having to wait for earlier downloads to complete to
perform the UI interaction (e.g., the Save dialog) for other
documents.

Obviously, HEAD doesn't work if the download uses POST instead of GET.

Also, how likely is it that HEAD request and the delayed GET request
wouldn't return matching headers?
