hosting.config(5) on Linux
The text 929d198ba172, as Debian 10 (Buster) shipped it.
Traffic Server domain hosting configuration file The hosting.config file (by default, located in /usr/local/etc/trafficserver/) allows you to assign cache volumes to specific origin servers and/or domains so that you can manage cache space efficiently and restrict disk usage. For step-by-step instructions on partitioning the cache according to origin servers and/or domains, refer to partitioning-the-cache. Before you can assign cache volumes to specific origin servers and/or domains, you must first partition your cache according to size and protocol in the volume.config file. After you modify hosting.config, navigate to the Traffic Server bin directory and run traffic_ctl config reload to apply your changes.
