Plain text please... Obvious question: Is port 443 open on the intermediate FW? But a quick check on google (hint, hint...) reveals this is the error you get when trying to pass through a proxy with an HTTP method that is not supported by the proxy. Check out this message and the faq link therein (it's about subversion but it's the same problem). http://svn.haxx.se/dev/archive-2002-06/1638.shtml In your case, the client must use the CONNECT method to tell the proxy to pass the requests directly to the internal server. For this to work you need: - mod_proxy_connect (not just mod_proxy) - AllowCONNECT 443 (or not present - this is the default) see http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#allowconnect for details.

Importance: High I have a SunFire V210 running Solaris 9 (4/04), Apache v2.0.53 & OpenSSL v0.9.7g, configured as a reverse-proxy for the real webserver, a Dell PE1750 running Windows Server 2003 & IIS 6.0. In between them is a Cisco PIX firewall & a Cisco CSS. Regular http works fine, but secure http gives me the following error: [error] (20014)Error string not specified yet: proxy: request failed to 172.16.4.101:443 (172.16.4.101) What the heck is going on here?
