SSL was working but I wasn't able to access SSL_CLIENT variables (like SSL_CLIENT_S_DN_Email). I added the directive 'SSLVerifyClient optional_no_ca' to my .htaccess file and now the variables are available. However, in IE the page loads normally the first time but after several refreshes I get the message "Internet Explorer cannot display the web page" and in Firefox the page opens as a blank file in a text editor - it won't load in the browser. The message from the subject line shows up in the ssl_error_log. Thanks!
