Comment 18 for bug 1426095

Vigos seems died, Alex.

But, you absolutely right: order is matter. When I re-ordering modules in config, problem is gone:

ecap_enable on

loadable_modules /usr/local/lib/ecap_clamav_adapter.so
ecap_service clamav_service_req reqmod_precache uri=ecap://e-cap.org/ecap/services/clamav?mode=REQMOD bypass=off
ecap_service clamav_service_resp respmod_precache uri=ecap://e-cap.org/ecap/services/clamav?mode=RESPMOD bypass=on
adaptation_access clamav_service_req allow all
adaptation_access clamav_service_resp allow all

acl HTTP_STATUS_OK http_status 200
loadable_modules /usr/local/lib/ecap_adapter_gzip.so
ecap_service gzip_service respmod_precache ecap://www.vigos.com/ecap_gzip bypass=off
adaptation_access gzip_service allow HTTP_STATUS_OK

This config works.
