## 13.9. SSL and CGI

One directive affects the writing of CGIs.

### 13.9.1. SSLExportClientCertificates

>     SSLExportClientCertificates
>     Server config, virtual host, .htaccess, directory

Exports client certificates and the chain behind them to CGIs. The certificates are base 64 encoded in the environment variables `SSL_CLIENT_CERT` and `SSL_CLIENT_CERT_CHAIN_`n, where n runs from 1 up. This directive is only enabled if `APACHE_SSL_EXPORT_CERTS` is set to `TRUE` in .../src/include/buff.h.
