I have bought a VPS server, setted the apache server. But I could only access the webpage from local,

I thought maybe the server did not recieveing access from outside.

I tried Firefox, but the access_log shows nothing accessed. But telnet http://www.59lt.com 80 and type nonsence code, I recieved following error:

and the access_log under /etc/httpd/logs also caught the acess,

This proved that the server do access request from outside, so why it ignore the normal request from Firefox, but choosed to recieving request from telnet?

Thanks.

PS: I'm using CentOS + yum installed apache(just now installed).
