mod_streamav module is an Apache 2 filter that scans the content of the Apache Brigades using the Clamav virus scanning engine.
Unlike mod_clamav, it operates on streams for higher performance.
mod_streamav was written by Tao Jin, who graduate from PKU, in China.
mod_streamav is an Apache filter, which is new feature of Apache 2.0. So mod_streamav cannot be run on Apache 1.3. (mod_streamav has been successfully tested on Apache version-2.0.54) And you should install Clamav properly.
#tar xvfz mod_streamav.tar.gz
#./configure --prefix=/somewhere/you want (if you don't change,the default path is /usr/local/lib)
Now, you can fine some libraries named like libmod_streamav.la libmod_streamav.so and so on in your prefix path.
#cp libmod_streamav.so /path to/apache2/moudles/mod_streamav.so
You have to edit the config file $apache2/conf/httpd.conf! Add following lines to this file
LoadModule streamav_module modules/mod_streamav.so
Ok, you can restart Apache, and do your test.
