mixing stable and testing debian packages.

["Louie Miranda" <louie@axishift.ath.cx>]

Is it possible to mix stable and testing deb packages?.
I mean, ex: I have libc6 2.2.5-11.5 and i want to make it  libc6 2.3.1-1

This happend to me when i downloaded mod_security.c
http://packages.debian.org/testing/web/libapache-mod-security.html

And installed it using dpkg -i libapache-mod-security_1.4.2-1_i386.deb

Now, im confused. Btw, if im going to put the testing distribution on
/etc/apt/sources.list
will my apt-* tools fixed this problem? And whats the correct configuration
to get testing deb packages.

I mean like this:

deb http://http.us.debian.org/debian stable main contrib non-free

Whats the url and will i change stable to testing?.
