You do not need an ICAP/eCAP service that Squid works well with. You
need an ICAP/eCAP service that integrates with your IDS. All production
ICAP/eCAP services are doing some specific adaptation (e.g., downgrade
image quality) or integrate with some specific adaptation library (e.g.,
ClamAV). They are useless to you unless they integrate with your IDS.

If there is no existing service that integrates with your IDS, you would
have to write and support one. If you go the ICAP route, many plug their
custom ICAP services into the free c-icap ICAP server. If you decide
going the eCAP route, then you do not need a server (eCAP is a
library/API, not a communication protocol, so your custom code plugs
directly into the host application such as Squid).
