mod_throttle

After installing 'mod-throttle' I was told I need to compile Apache with
mod_so. Please excuse my ignorance.

1. Where do I issue this command, in which directory?
'./configure --enable-module=so'

2. How do I compile it and copy my httpd binary over?

3. How do I go back to mod_throttle source, make clean?

4. How do I reconfigure mod_throttle? Do I just start over?

Thanks a lot.
