<VirtualHost server1.com:443>
    ServerAdmin
    DocumentRoot /data1/apache/htdocs/server1
    SSLEngine on
    SSLCertificateFile /data1/apache/conf/ssl.crt/server1.crt
    SSLCertificateKeyFile /data1/apache/conf/ssl.key/server1.key
</VirtualHost>
<VirtualHost server2.com:443>
    ServerAdmin
    DocumentRoot /data1/apache/htdocs/server2
    SSLEngine on
    SSLCertificateFile /data1/apache/conf/ssl.crt/server2.crt
    SSLCertificateKeyFile /data1/apache/conf/ssl.key/server2.key

for each of virtul host in apache?
