Welcome to WebmasterWorld Guest from 126.96.36.199
Under security, I noticed the comment:
"Every XAMPP demo page you are right now looking at is accessible for everyone over network. Everyone who knows your IP address can see these pages."
Does this mean that anyone who knows my IP address and knows the path to my xampp installation can see all my files online, really?
Only people on your network can see you.
However, you can stop that happening! Open up the httpd.conf file which is the configuration for Apache Web Server, by default located in "C:\xampp\apache\conf".
Near the top is the line "Listen 80", alter this to "Listen 127.0.0.1:80". This will tell Apache to only accept connections from the machine it is running on.
