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 …
Each line in the hosting.config file must have one of the following formats:
hostname=HOST volume=NUMBERS domain=DOMAIN volume=NUMBERS
where HOST is the fully-qualified hostname of the origin server whose content you want to store on a particular volume (for example, www.myhost.com); DOMAIN is the domain whose content you want to store on a particular partition (for example, mydomain.com); and NUMBERS is a comma-separated list of the partitions on which you want to store the content that belongs to the origin server or domain listed. The partition numbers must be valid numbers listed in the volume.config.
Note: To allocate more than one partition to an origin server or domain, you must enter the partitions in a comma-separated list on one line, as shown in the example below. The hosting.config file cannot contain multiple entries for the same origin server or domain.
When configuring the hosting.config file, you must assign a generic volume to use for content that does not belong to any of the origin servers or domains listed. If all volumes for a particular origin server become corrupt, Traffic Server will also use the generic volume to store content for that origin server.
The generic volume must have the following format:
hostname=* volume=NUMBERS
where NUMBERS is a comma-separated list of generic volumes.
The following example configures Traffic Server to store content from the domain mydomain.com in volume 1 and content from www.myhost.com in volume 2. Traffic Server stores content from all other origin servers in volumes 3 and 4.
domain=mydomain.com volume=1 hostname=www.myhost.com volume=2 hostname=* volume=3,4
