是否需要SSL证书可以让他们在Geotrust中低至17美元，如果需要还是一个在hostgator或godaddy以及他们会安装它，如果他们作为一个主机...一旦附加到域名应该显示在iframe中的FB中的网站或网页...也因为之前的海报需要有域一样的一个在FB中使用iframe，这样就可以正确显示...
希望帮助

Yep you require a SSL Certificate can get them as low as $17 in Geotrust if need be or a dearer one in hostgator or godaddy as well and they will install it for if have them as a host... once attached to domain should show the site or webpage in FB within Iframes... Also as the previous poster need to have domains the same one using the iframes in FB as that is where you want it right displayed... Hope helps Rick Ling
