httpd.conf

The Apache's httpd.conf file uses what are called Directives.
The file itself is a text file. It can be open in a text editor.
The syntext in the file looks like XML or HTML.

Most Directives have opening and closing tags and the parameters go inside the open
and closing tags.


There are also comment tags which is just a pound sign #



Most Directives have notes on what they do.
For example the Directive "Listen 80" in the httpd.conf file for the Xampp server around line 53 if your text editor has line numbers.
You if you where to edit this in your text editor and chage the number to 8080 then restarted Apache you would view your sites on port 8080 http://localhost:8080.
not http://localhost/ . The MAMP server uses port number 8888.
