Hi, Also, I configured the Apache for client-authenticated SSL, and hit the https://<hostname>/test URL, and the dump_envvars() output only one additional variable:
In ap_headers_insert_output_filter: About to call dump_envvars... In iterate_function: [UNIQUE_ID] => [T993fkjX4QkAAHanMQwAAAAA] In iterate_function: [HTTPS] => [on] In ap_headers_insert_output_filter: Returned from calling dump_envvars... but not the other SSL-related variables, but if I add: SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars to the <VirtualHost> in extras/httpd-ssl.conf, WOOHOO(!), I get a bunch of SSL stuff :)...
