At the ICAP server software/application level, each server "works" in its own way, irrelevant to Squid. > the example on this page: https://github.com/netom/pyicap > 127.0.0.1 - - [06/b'Mar'/2019 23:22:58] respmod_OPTIONS not found > 127.0.0.1 - - [06/b'Mar'/2019 23:22:58] code 404, message b'Not Found' I know nothing about that ICAP framework, but you probably need to follow its README directions and define the respmod_OPTIONS method (among other things): > You can use a framework by importing stuff from the pyicap package, > extending the protocol handler class and starting the server, passing > your handler to it: ... In other words, that specific ICAP code is not a ready-to-use ICAP server but a _framework_ for building an ICAP server (that does what _you_ want it to do). If you need an ICAP server to do X, then you should either find an existing ICAP server that already does X or build a new ICAP server that does X. The latter should be accomplished either by using an existing ICAP library/framework (like the one you found above) or by writing a loadable module/plugin/adapter (that does X) for an existing ICAP server that accepts such adapters. Squid wiki has a bit more info about ICAP: * https://wiki.squid-cache.org/SquidFaq/ContentAdaptation#ICAP * https://wiki.squid-cache.org/Features/ICAP The first page also discusses (and compares) various ICAP alternatives.
