Yep, I did that and port 80 works like a dream.

When you say:

>Then, set up a virtual server on port 443 with the same proxy stuff.
>You reference the certificate file there.

this is the bit that bothers me.

Here's my virtual host:

<VirtualHost revproxy:443>
        ServerName slrsdct1.internal.standardlife.com
        ErrorLog /oem/apache-mod_ssl/logs/error_log
        ProxyPass / https://webserver/
        ProxyPassReverse / https://webserver/
        SSLEngine On
        SSLCipherSuite ALL
        SSLCertificateFile /oem/apache-mod_ssl/conf/ssl/revproxy.crt
        SSLVerifyDepth 3
        SSLCertificateKeyFile /oem/apache-mod_ssl/conf/ssl/revproxy.key
</VirtualHost>

I can make an SSL connection to this virtual host; the browser indicates
that encryption is in use.
The certificate/key that the reverse proxy is using is specified by the
SSLCertificateFile and SSLCertificateKeyFile directives.

The reverse proxy should now make an SSL connection to webserver (this is
running IBM HTTPServer, IBM's packaged Apache). webserver has it's own
self-signed certificate. I can make SSL connections to webserver with a
browser satisfactorily, but the browser alerts me that it doesn't trust the
certificate (because it's self-signed) and I have to click through.

I imagine that revproxy doesn't trust the certificate either, which is
causing the problem. Perhaps it's something else, but I am pretty sure I
need to tell revproxy about webserver's certificate within httpd.conf. I
can't find a suitable directive in the docs.

BTW this is Apache/1.3.24 with mod_ssl-2.8.8-1.3.24 on AIX 4.3.3

I have also been trying to do this with another proprietary product that
I'm not going to mention; it doesn't work (the supplier is working on a
fix) and I really don't like the software. I would love to prove that
Apache and mod_ssl are up to the job.

Many thanks in advance!

Michael

Set up two virtual servers for the same IP, one on port 80 (with just
simple
proxy rules).  Confirm this works.

Then, set up a virtual server on port 443 with the same proxy stuff.  You
reference the certificate file there.
