Hi folks,

The multiple subdomain (HOST_REGEXP) looks not working in TC version we are 
using. However, after checking the code in latest master branch, I would 
suspect if this is fully supported:

1. Based on the code, Traffic Router may not fully support HOST_REGEXP with 
“set_number” not equal 0. The cr-config generated will only include the first 
HOST_REGEXP into the “domains” field for each delivery service. So the 
auto-zones will not be generated for other HOST_REGEXP.

2. For HTTPS delivery service, the SSL certificate will only be generated for 
the first HOST_REGEXP.

Have anyone of you are using multiple HOST_REGEXP in your delivery services? 
Please correct me if my understanding is wrong.

If we want to fully support multiple subdomain (HOST_REGEXP), should we do:

For item 1) above, expand all HOST_REGEXP and add into “domains” field for each 
delivery service in “cr-config”. Is there any special reason to only include 
the first one?

For item 2) above, add SAN in SSL certificate for all HOST_REGEXP other than 
the first one (set_number == 0)?


Thanks,
Zhilin
