JFrog documentation (http://www.jfrog.com/confluence/display/RTF/Docker+Repositories) show how to use nginx as front end for Artifactory/Docker hosting :
If you're using Apache HTTPd and mod_jk, you could do it too. Just enroll mod_rewrite.

ServerAdmin admin@company.com

SSLCertificateFile "/etc/apache2/ssl.crt/artprod.company.com.crt"
