Question about loading one more ecap-adapter module

Hi.

Today, I configured squid to load two ecap-adatper when running. The configure file is as following.

--------------------------configure file--------------------------------------
loadable_modules /adapter/cygmodifying.dll
ecap_service ecapModifier respmod_precache \
    uri=ecap://e-cap.org/ecap/services/sample/modifying \
    victim=</body> \
    replacement-src=inject.html \
adaptation_access ecapModifier allow all

loadable_modules /adapter/cygreplace.dll
ecap_service ecapReplace respmod_precache \
        uri=ecap://e-cap.org/ecap/services/sample/replace \
adaptation_access ecapReplace allow all
--------------------------configure file end--------------------------------------

The vectoring_point option of the two ecap-adapters are all configiured as respmod_precache.
That is, The ecapModifier and ecapReplace are configured to be activated at the same point.

But, When I running squid autually, I find that only one works. Only the ecap-adapter which's
configuration is in front of the configure file works.

So, Is is possible let all of them to work . If possible, How?
