10.5.66. Configuration Directives for SSL
The directives in
/etc/httpd/conf.d/ssl.conf file can be configured to enable secure Web communications using SSL and TLS.
10.5.66.1. SetEnvIf
SetEnvIf sets environment variables based on the headers of incoming connections. It is not solely an SSL directive, though it is present in the supplied /etc/httpd/conf.d/ssl.conf file. It's purpose in this context is to disable HTTP keepalive and to allow SSL to close the connection without a closing notification from the client browser. This setting is necessary for certain browsers that do not reliably shut down the SSL connection.
For more information on other directives within the SSL configuration file, refer to the following URLs:

For information about setting up an Apache HTTP Secure Server, Refer to the chapter titled Apache HTTP Secure Server Configuration in the System Administrators Guide.
Note
In most cases, SSL directives are configured appropriately during the installation of Red Hat Enterprise Linux. Be careful when altering Apache HTTP Secure Server directives, misconfiguration can lead to security vulnerabilities.
