You did not tell Squid to use request_chain. You told Squid to use
ecapBlockSiteRequest and only ecapBlockSiteRequest. adaptation_access
directive selects which service (or a group of services) is going to be
used. Your directive always selects ecapBlockSiteRequest.

You may declare 100 adaptation services, service sets, and service
chains. How should Squid know which service (or set or chain) it should
send the request to? Squid evaluates adaptation_access rules to answer
that question. The first applicable matching rule determines the service
(or set or chain) that will be used at a given vectoring point for a
given transaction.
