You may found the answer to your question, But I ma reading through this thread and found your question.

You will not find any file located at /etc/htmld using Spotlight

find the file

1. Open terminal from <Application><Utilities>
2. This will open a command window on your desktop
3. At the prompt type httpd -V
you should see a report

NOTE : this report will tell you that with MAC OSX
the file you are looking for is located at
-D SERVER_CONFIG_FILE="/etc/httpd/httpd.conf"
3. use this command at the command line prompt
cd /etc/httpd
4. this will switch you to the directory/folder
named /etc/httpd the configuration file is located in this file - folder path

If you have not received an answer yet I hope this will be of any use for you
