Hi,

I'm trying to get Apache Reverse Proxy to do two things.  1. For this particular issue I want to know how I get the Reverse Proxy to send the URL out on 443 instead of 80?  I've been able to get this far almost accidently.  2. Eventually I'd like to be able to pass all traffic straight through.  If the second part is sufficiently different and complex enough I can open a second question.  I lumped them together because they seemed closely related.


1. BrowserClient:443 --ssl--> ApacheReverseProxy:443 --clear  --> TomcatServer:80.

2. Browser Client downloads Java applet.

3. JavaApplet:443 --ssl--> ApacheReverseProxy:443 --ssl--> TomcatServer:443 --clear--> Host:23

Items #1 and #2 work correctly.

Item #3, the Java applet going into Apache Reverse Proxy is working correctly.

The problem is that the Java applet coming out of the Apache Reverse Proxy is coming out on port 80.  Tomcat Server expects 443.


Here are relevant sections of httpd.conf.


<VirtualHost _default_:443>
   ServerName ApacheReverseProxy
   ProxyRequests on
   ProxyPass    /                  http://TomcatServer/
   ProxyPassReverse /              http://TomcatServer/
   AllowCONNECT 443
   ProxyPass    /mcs/               https://TomcatServer:443/
   ProxyPassReverse /mcs/           https://TomcatServer:443/
</VirtualHost>

<VirtualHost ApacheReverseProxy>
   ServerName ApacheReverseProxy
   ProxyRequests on
   ProxyPass    /                  http://TomcatServer/
   ProxyPassReverse /              http://TomcatServer/
</VirtualHost>

I get this message in my error log but I can't tell if it is
relevant because my SSL connections do work.
[Fri Jul 18 10:08:42 2003] [crit] (98)Address already in use:
make_sock: could not bind to port 443

I've also tried using rewrite with various incantations.

I am able to set the port the Java client uses but would prefer to use 443
coming back into Apache Reverse Proxy.  I tried setting up a virtual host as
well listening on 444 and then redirect back to Tomcat Server on 443 but that
didn't work.

FWIW this is the url sent from the Java client
GET /mcs/components/terminal3270/JavaClient/com/attachmate/emulation/printer/Printer3270.class
HTTP/1.1\r\n
