Thanks Zhilin- Could I use a domain of just “topdomain-cdn.com” or does it require a minimum of three levels?
Is configuration just in delivery service or does the domain_name parameter need to be modified too? > On Jun 21, 2017, at 4:56 AM, Zhilin Huang (zhilhuan) <zhilh...@cisco.com> > wrote: > > Hi all, > > I am working on a feature to support custom delivery service domain. > > Currently in traffic ops, you can configure a “HOST_REGEXP” for a delivery > service with pattern like: > 1) .*\.my-subdomain\..* > 2) my-subdomain.topdomain.com > > I think pattern 1) is well known by all of us.
