====== cPanel guide ======

===== ModSecurity =====

  * introduced ModSecurity method to ensure posting site-wide, text submit to server will be check before run
  * a 406 error will occur if the text is a bit sensitive
  * normally it need to be configured on server side for whitelist

===== domain pointing =====

  * domain need 15 min to refresh the pointing
  * local browser or rounter has around 24 hour to refresh the cache
  * brower history and cache need to cleared to update the domain pointing lookup

===== Primary domain, Add-on domain and Sub-domain =====

**Primary domain**
  * Primary domain is the main domain pointing to your /main_root/public_html, also the main name of the cPanel
    * **subdomain**, it is sub of primary domain, subdomain.primarydomain.com, and it is usually under /main_root/public_html/sub_domain/, it also can go /main_root/subdomain_folder/

**secondary domain**
  * A secondary domain functions as an independent entity, with its own email accounts, websites, directory structure, statistics pages, bandwidth, and recording. The only real connection between a primary domain and a secondary domain are the resources and feature limits of a shared service. For example, if your service allows for ten email accounts, you can have five on your primary domain and five on your secondary domain.

**addon domain** (cPanel's way of calling secondary domain)
  * addon domain is a separate domain point to additional websites, it can be under /main_root/addon_domain_folder/ or it can be under /main_root/publich_html/addon_domain_folder, it has no link to primary domain, and search engine will treat them separately.
  * However, unlike primary, it doesn't have its own cPanel, it still can create email account, redirects, install and subdomains, but for ftp acc, the username will be username@primary_domain.com and ftp server still shows as primary_domain.com. Thus other than ftp acc, it is able to show no connection to primary domain
  * If you make sure no url link from primary domain to addon domain, the search engines won't find them through primary domain. such as primary_domain.com/addon_domain_folder, or addon_domain_subname.primary_domain.com. Thus it is better to put folder structure as primary domain web sits at /main_root/publich_html, addon domain web sits at /main_root/addon_domain_folder

**parked domain**
  * parked domain is like alias of primary domain, so always pointing to same primary location

**Alias domains**
  * Alias domains display the primary domain's website with a different domain name/URL
