apache logs


in the beta when you enabled the apache webserver it had log files ( i thought you could adjust settings on them too, but i can't quite remember ). I was looking for the logs today and didn't see them anywhere, i couldn't find any settings for them either. Anyone know where they are or how to enable them?
Are you looking for the access and error logs which are in /var/log/httpd? And to modify, you have to edit the Apache config file, /etc/httpd/httpd.conf and change ErrorLog and/or CustomLog.
I was browsing my apache access_log, and i came across a few things that have me confused and a bit paranoid. I have found some strange entries, for example, - - [06/Apr/2001:22:07:20 -0500] "GET http://www.spedia.net/sp_login.htm HTTP/1.1" 404 284

and - - [08/Apr/2001:12:02:45 -0500] "GET http://www.ebay.com/ HTTP/1.1" 200 1358

and - - [03/Apr/2001:18:46:13 -0500] "GET http://www.intel.com/ HTTP/1.1" 200 1358

Can anyone explain what these mean, or why someone would be trying to get to intel or ebay through my computer? Should i be concerned, or am i being overly paranoid?
