Thank you for answer.
I am running XAMPP on Windows XP SP2
You mentioned about port 80, I found this service (http://canyouseeme.org/
) to check whether port 80 is open or forwarding
If I START Apache, it show port 80 is open & my ISP not blocking it.
If I STOP Apache, than it say can not see port 80.
Is this a security problem?
I use internet at home, and work on web design on XAMPP, and at the same time connected to internet to find information. I do sometime experience very slow browsing while working. Internet sites that open fast few minutes ago suddenly load very slow. I have to disconnect and reconnect internet to get back normal browsing speed.
Now I wonder could this be related to XAMPP opening port 80 or something accessing my pc that cause slowdown? or am I just being over concern?
Thank you very much
