reducing size of apache instances

[Gareth Brown]

   Here's a few you can disable:
   mod_status, mod_info (both give extra unnecessary info about server)
   and mod_include (allows include statements in html files).  These
   aren't recommended anyway unless you really need them as they create
   some level of security concern.
   mod_userdir is only needed if you are allowing users to have webpages
   from home directories
   mod_ssl, only if you're going to use ssl
   mod_rewrite only if you will be rewriting webpage names to something
   else
   mod_auth_basic and mod_auth_digest only if you're going to add http
   authentication to any of your webpages

     My Apache 2.2 instances are running about 18 Meg each. I've been
     thinking about doing something to trim these down, and I think
     tomorrow is the day to take action. They are getting out of hand.
     I've done a bit of research on this. I think the way to get started
     is to eliminate unused modules. Problem is, I know which ones I
     need, since I purposefully added them. I *don't* know which ones I
     don't need, if you see what I mean, since I inherited them from the
     default configuration.
     I assume that some are critical to the basic operation of Apache. I
     am hoping I can google a list of these tomorrow. Obviously these
     I'll have to live with.
     But what about the set that is left after I remove the ones the
     system needs, and the ones I need? How do I know which ones I can
     safely turn off? All I can think of is a trial and error process
     (i.e., turn them off one by one and see if anything breaks.)
     Is there a better way?
