Well, first off, let me confess my ignorance of how FrontPage works. Now, I
will talk about what I do know. Maybe someone with a little knowledge of
FrontPage will be able to piece together why this doesn't work.

mod_backhand actually plays "man-in-the-middle" wth regards to proxying HTTP
requests. It takes the liberty of upgrading non-persistent HTTP sessions to
persistent sessions during proxying.

This allows mod_backhand to maintain open TCP/IP sessions and pipeline the
HTTP requests/responses between itself and another server, while the client
never knows the difference.

Client -> HTTP/1.0 no keepalive -> mod_backhand -> upgrades to keepalive ->
selected server -> HTTP/1.0 with keepalive -> mod_backhand -> HTTP/1.0 no
keepalive -> Client.

Because of this, mod_backhand must know the internals of HTTP and counts on
the request and response being valid HTTP/1.0 requests... If frontpage
requires a "change" to the HTTP protocol, that would completely break
mod_backhand's ability to HTTP redirect the request. But, perhaps the HTTP
redirection methods will work for you:

Hope this helps some :-)
