Configure apache to use wildcard certificate

To configure apache virtualhost for using wildcard certificate use:

<VirtualHost *:443>
    ServerAdmin saurabh@example.com
    DocumentRoot /home/example/public_html/
    ServerName www.sbarjatiya.com
    ErrorLog logs/www.sbarjatiya.com-error_log
    CustomLog logs/www.sbarjatiya.com-access_log combined
    SSLEngine on
    SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
    SSLHonorCipherOrder on
    SSLCipherSuite "EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA!RC4:EECDH:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS"
    Header always set Strict-Transport-Security "max-age=31536000"
    SSLCertificateFile /etc/httpd/conf/sbarjatiya_wild_cert/sbarjatiya.com.crt
    SSLCertificateKeyFile /etc/httpd/conf/sbarjatiya_wild_cert/sbarjatiya.com.key
    SSLCertificateChainFile /etc/httpd/conf/sbarjatiya_wild_cert/ca-chain.crt
</VirtualHost>

Here ca-chain.crt can be generated using certificates from zip file received in email as follows:

cat COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt >> ca-chain.crt
