adding new modules in apache

[nlimbu healthnet org np]

Hi all,

I have a newbie question regarding installation of program. I have already
installed Apache from installation CD of RH. Now, I need to recompile
apache again inorder to add some feature. What should I need to do?

1) In order to recompile, do I need to download apache*tar.gz file and and then 
compile it with make command? 
2) Do I need to remove the previous apache installed which has been already 
installed from RH installation CD?
3) What will happen to the path for the files of newly installed apache? Will it be 
same like previous or do we need to specify? Do I need to make services of httpd 
again manually inside /etc/rc.d/init.d? 
4) Is it possible to add/remove feature/module via rpm package of apache?

With Regards
