Symptom

Mixed-content warnings, such as:

Internet Explorer: Only secure content is displayed.
Firefox: Firefox has blocked content that isn't secure.
Chrome: This page includes script from unauthenticated sources.

Possible Cause

A secured page (HTTPS) contains unsecured links (HTTP) to some resources (images, scripts, etc.).

Solution

Configure the SSL Offload Header Value as required by your load balancers.

Examples:
- Citrix supports custom headers and recommends using SSL_REQUEST.
- Weblogic uses a fixed header of WL-Proxy-SSL.
- BigIP/F5 supports custom headers via their iRule rewrite function.
