Origin Configuration

Each origin is required to have a JSON configuration object available in the Redis backend under the key
jasima:config:<canonical host>.
The following keys are meaningful in this object:

Key	Description	Default	Example
headers	Append additional headers to the request sent to the origin.	No additional headers are added.	{"X-Example": "Hello"}
host_connect	Override the hostname that is used to connect to the origin. This can be useful in the case that the origin is begind a CDN that you want to avoid having to traverse, either due to DDoS protection tools being falsely triggered or simply to save costs.	The canonical host is used.	"real-origin.example.com"
host_header	Override the hostname that is used as the Host header when connecting to the origin.	The canonical host is used.	"news.example.org"
host_ssl	Override the hostname that is used for TLS SNI and for verification of the upstream's TLS certificate.	The canonical host is used.	"news.example.org"
matomo_site_id	The site ID to use for Matomo tracking.	No tracking code is added to HTML pages.	20
rewrite_case_insensitive	Rewrite references to other domain names using a case-insensitive match. This requires the use of the PCRE engine which is approximately 10% of the speed of the Lua pattern matching engine, so only enable if required.	Domains are matched based on the case in the pool mapping.	true
rewrite_disable	Disable content rewriting for this host. This disables both URL rewriting, and the addition of Matomo tracking code, but not the replacement of absolute links to the canonical hostname with relative links.	Rewriting is enabled.	true

Note: the default case applies when the key is omitted.
