This is with apache 1.3.x. Running apache 2 isn't an option due to some web applications using older versions of mod perl. I want to use apache to proxy ssl connections to a backend plain http server. The backend server is mongrel (http://mongrel.rubyforge.org/) which is used to run ruby on rails web apps. Apache would be configured to require ssl client certificates issued by our ca. What I want is to somehow pass the mod_ssl environment variables to mongrel when the request is proxied. I've tried using mod_rewrite, and while it handles the proxying just fine it's not passing the ssl environment. This is the configuration that isn't working for me. I've also tried setting an arbitrary test environment variable ([E=TESTVAR:test,P]) without any luck. RewriteRule ^/xml/(.*) http://localhost:88/xml/$1 [E=SSL_CLIENT_CERT:%{SSL:SSL_CLIENT_CERT},P] So is there a way to do what I want with apache 1.3.x? chris --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
