Some certificates issued by Certificate Authorities require a third certificate, often referred to as an intermediate certificate. This additional certificate provides a chain path from the CA to the certificate issued to your site.

While some CAs use intermediate certificates, others do not. If you have questions on whether or not you should have received an intermediate certificate from your CA vendor, contact your CA vendor.

If a CA certificate has been installed, and an SSL error appears when browsing the Virtual Service, it is likely that an intermediate certificate needs to be installed.

Uploading several consecutive intermediate certificates within a single piece of text, as practiced by some certificate vendors such as GoDaddy, is allowed. The uploaded file is split into individual certificates.
