Password authentication to TivoWeb behind Apache proxy

["Bricknell, Tony" <tony.bricknell@xxxxxxxxxxxxxxxxxxx>]

I hope someone here can offer some advice to a linux newbie.  I've spent
the past week trawling google, apache.org, contribs.org and many other
sites but none explain how to do what I thought was a simple task...

Tivo is on my internal network.  SME server is running a virtual domain,
tivo.mydomain.com and reverse proxying it out to the tivo box thereby
enabling remote tivoweb access (after following a web posting showing how
to create a file and template-expand it only to find it didn't work, I
found a contrib giving a simple proxypass panel in the server-manager). 
However, I want Apache to request user/password before allowing access to
Tivo.

All I've read discusses making changes to httpd.conf and putting a password
file in the root of the web site you're hosting.  But I can't do that with
TivoWeb.  And besides, it's not hosted on the SME box.

I'm sure some here have remote Tivoweb access through an Apache reverse
proxy.  But how do you ensure only authorised access?

TIA for helping me during this steep learning curve (now I know what my
father felt like when he took delivery of his first PC a year ago!)
