Feature: eCAP support
Goal: Improve Squid3 content adaptation performance by 20+%, remove the need for an ICAP server
Version: 3.1
Status: Ready for initial testing; code in Squid3 trunk
Developer: AlexRousskov
Configuration
Install libecap and build Squid with the --enable-ecap configure option. Install an adapter module. The library and sample adapters are available from the eCAP site.
Configure Squid to load an adapter module and specify which services the module provides:
loadable_modules /usr/local/lib/ecap_adapter_minimal.so ecap_service eReqmod reqmod_precache 0 ecap://e-cap.org/ecap/services/sample/minimal ecap_service eRespmod respmod_precache 0 ecap://e-cap.org/ecap/services/sample/minimal
Among all dynamically loaded services, only the services matching ecap_service configuration are enabled by Squid.
Now you can setup ACLs to direct traffic to the configured services.
adaptation_service_set reqFilter eReqmod adaptation_service_set respFilter eRespmod adaptation_access respFilter allow all adaptation_access reqFilter allow all
ICAP and eCAP services can co-exist. ACLs control which service gets to process the HTTP message.
