Enable SSL for Virtual Hosts

The Apache server supports virtual hosts, which are multiple Web hosts that are run from a single Apache binary. Apache virtual hosts can be name-based or IP-based. Name-based virtual hosts can share a single IP address, while IP-based virtual hosts require a different IP address for each virtual host.

Apache virtual hosts using the SSL protocol:

• Must be IP-based due to limitations in the protocol.
• Must have virtual host containers in the Apache configuration file for both secure (HTTPS) and not secure (HTTP) requests.

The following is an example of a secure (HTTPS) virtual host:

<VirtualHost 10.0.0.1:443>
DocumentRoot ".../htdocs/site1"
ServerName www.site1.net
ServerAdmin webmaster@site1.net
ErrorLog logs/covalent_error_log_site1
TransferLog logs/...
SSLEngine on
SSLCertificateFile /www.site1.net.cert
SSLCertificateKeyFile /www.site1.net.key
CustomLog logs/cipher_log_site1 \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
</VirtualHost>
