ProxyPass with redirect to https on other port

[tsltsl]

Hi,
I have a problem I can't seem to solve:

I run an apache on port 80 and 443 which needs to connect to another apache on port 9080 and 9443.

I use for non-ssl the proxy directive:
ProxyPass /nonssl

http://127.0.0.1:9080/nonssl

ProxyPassReverse /nonssl

http://127.0.0.1:2080/nonssl

This works fine, but when it comes to port 9443 I get into problems. I use:
ProxyPass /ssl

https://127.0.0.1:9443/ssl

ProxyPassReverse /ssl

https://127.0.0.1:9443/ssl

What happens is that it is connecting correct to the /ssl directory on port 9443, but I need to redirect the users browsers to https if they are on http!

I have tried writing Redirect and Rewrite directives to no avail.

I put them after the proxy directives in the conf. i.e

Redirect

http://www.domain.tld/ssl

https://www.domain.tld/ssl

or
RewriteRule ^/ssl(.*)$

https://www.domain.tld/ssl/

[L]
or
RewriteRule ^/ssl(/)?$

https://%{HTTP_HOST}/ssl/

[R,L]
or
RedirectMatch ^/ssl(.*)

https://%{HTTP_HOST}/ssl/$1

If I manually type in

https://www.domain.tld/ssl

it works fine though.

Anyone with ideas?
Thanks!
