Configure Multi Site Origin
***************************

1) Create “cachegroups” for the origin locations, and assign the appropriate parent-child relationship between the mid cg's and org cgs (click the image to see full size):

2) Create a profile to assign to each of the origins:

4) assign the org servers to the delivery service that will have the multi site feature

5) Check the multi-site check box in the delivery service screen and make sure that Content Routing Type is set to HTTP_LIVE_NATL:

7) Configure the mid hdr_rewrite on the delivery service, example: ::

	cond %{REMAP_PSEUDO_HOOK} __RETURN__ set-config proxy.config.http.parent_origin.dead_server_retry_enabled 1 __RETURN__ set-config proxy.config.http.parent_origin.simple_retry_enabled 1 __RETURN__ set-config proxy.config.http.parent_origin.simple_retry_response_codes "400,404,412" __RETURN__ set-config proxy.config.http.parent_origin.dead_server_retry_response_codes "502,503" __RETURN__ set-config proxy.config.http.connect_attempts_timeout 2 __RETURN__ set-config proxy.config.http.connect_attempts_max_retries 2 __RETURN__ set-config proxy.config.http.connect_attempts_max_retries_dead_server 1 __RETURN__ set-config proxy.config.http.transaction_active_timeout_in 5 [L] __RETURN__

8) Turn on parent_proxy_routing in the MID profile.
