I believe I need to proxy SSL. I have one Apache server, with SSL, and am using ProxyPass to get https://server1/app/ to proxy to https://server2/app/ server2 is set up to use certificate details for authorization. I found http://httpd.apache.org/docs/2.2/mod/mod_ssl.html There are an awful lot of SSLProxy* directives, and I'm not sure what all I need to get this working. I added SSLProxyEngine on and got errors like: [Wed Jul 22 23:02:56 2009] [warn] Proxy client certificate callback: (server1:443) downstream server wanted client certificate but none are configured [Wed Jul 22 23:02:56 2009] [error] (502)Unknown error 502: proxy: pass request body failed to [2001:480:10:61:250:56ff:fe2f:f1c3]:443 (server2) I'm not sure why it's trying to talk IPv6 to server2 I added a hosts entry with the correct IPv4 address, just to eliminate that issue, but I get the same error. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * *********************************************************************** --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
