The concept

The main goal of this project is to create an ICAP server (RFC 3507) implementation in C++ to use the power of object oriented programming.

Starting from scratch, the server is developed with a modular architecture in mind. The server core (written in C++) will handle the client requests, manage workers (child processes) etc. and will provide basic handlers to serve ICAP requests.

To extend this core functionality the idea is to have pluggable modules (like apache server modules). These modules will provide features like content filtering, anti-virus scanning etc. and to make it easier to write (and faster to implement) such modules there is hope to exploit python programming language.

Bugs and Feature Requests

Please report all bugs and feature requests under issues.

Compiling from source

If you are using the github source then first you need to initialise autotools.

$ libtoolize (glibtoolize in OS X)
$ aclocal
$ autoheader
$ autoconf
$ automake --add-missing

After that you can use the usual ./configure && make



This is the (long awaited) python interface module. It provides a template for any other python interface module implementations either as C++ module template or as a C++ interface for python modules.


Use the following to create the binaries with debug symbols

$ ./configure CXXFLAGS="-g -O0"

config file

The default config file location is /etc/bitz/bitz-server.conf but this can changed using the --with-config option when you run configure.


$ ./configure --with-config=/[path to source code]/conf/bitz-server.conf

valgrind checks

$ valgrind --leak-check=full --read-var-info=yes --trace-children=yes --suppressions=test/valgrind.supp --log-file=valgrind.log ./src/bitz-server --debug
