This module allows writing services for the c-icap server in pure Ruby.
It was tested with 1.9.1p378 patched with the bind_ruby_stack() patch (see below).
This is an experimental and not a production grade software
It wasn't used since the days of 1.9.1, so there's a slight chance that 1.9.2 will work without the patch, but I seriously doubt it.
You can read about the patch here: http://redmine.ruby-lang.org/issues/show/2294
The patch for 1.9.1p378 cab be found here: http://redmine.ruby-lang.org/attachments/download/651/ruby_bind_stack.patch
The patch for 1.9.2p0 can be found here: http://redmine.ruby-lang.org/attachments/download/1153/ruby_bind_stack_1.9.2p0.patch
In c-icap.conf:
Service foo /some/path/foo.rb
See examples/icap.rb for better understanding what should be implemented by a service.
The name of the service class name must be IcapService, as this is the name the module will search for.
You will need to call .force_encoding('ASCII-8BIT') on the response body, unless it's
already in ASCII-8BIT encoding.
Even with the patch I'm not sure that it's possibe to embed several Ruby interpreters in one process. You may want to limit the number of worker threads to 1 (ThreadsPerChild 1) and increase the number of c-icap processes.
