Davenport WebDAV-CIFS (SMB) Gateway

Okey I have a apache webproxy that I use to proxy certaint subdomains to
resources behind the proxy..

this setting below works ok, BUT.
<init-param>
<param-name>contextBase</param-name>
<param-value>https://mydomain.com/davenport/</param-value>
</init-param>

the apache rewrite engine that is also used when proxying, can rewrite the
adress for me, without this davenport setting. but it cannot rewrite the
protocol. so if my front end server(apache proxy) is using https adress,
and davenport is using http.... the adresses would be wrong. however using
the contextBase setting can correct this. but I would rather just be able
to change protocol part instead, as I want different adresses used on the
same davenport.

so what I propose is a setting or a method, so I can just change the
protocol part of the links. if I had a contextbaseProtocol setting like
this:
<init-param>
<param-name>contextBaseProtocol</param-name>
<param-value>https://</param-value>
</init-param>

It would be good for me. because it's not likly that I want to have both
http and https access to this resource, but it's likly that I want
different adresses to the same resource...
