First, we need to create a server group and then use Squid to reverse cache Port web80 to accelerate our website. major portal websites such as 163, sina, and chinaitlab are basically using this technology. the advantage is that it has a great advantage. For example, it accelerates the network and protects against hackers (because they see CDN hosts). This is a reverse set using Squid.
First create a server group and then use Squid to reverse cache Port web80 to accelerate your website.

JQuery animate and CSS3 are combined to achieve slow-moving Chase Effect. Source Code download is provided. jquerycss3
Both CSS3 and jquery can achieve a slow chase effect. However, considering the compatibility of browsers, we recommend that you use the jquery animate method.

A few days ago, I got a shell from the station, windows2000 system. The Elevation of Privilege was successful, 3389 was not enabled, and 3389 was opened. After the server was restarted, lcx forwarded and 3389 logged on.
After entering the server, we found that only one host in the same C segment is 192.168.0.50.
So I felt strange. How can we say that the unit of this station is also small and small? How can we get one .... As a result, the server is in the DMZ zone again to communicate with t
Zabbix monitoring firewalls and switches are transmitted through the SNMP protocol for data and data analysis, which I will explain below with the Dell Firewall SonicWALL 3400 series and switch N4032. Since the Zabbix server is already installed, it is now only possible to install the SNMP protocol on the fire switch on the firewall and send the data as a client.(i) Monitoring firewallsFirst, log in to the firewall and locate the firewall's monitoring

Also can only say at present, see the evolution direction of ASA, probably do not know when to import.

What is the function of the diode in AC DC power? Output voltage? The output current is determined by the maximum rated current of the diode. The 1n4007 diode (Universal Silicon Rectifier diode M7) is rated at 1 A and the output current is less than 1 a.
If you want to understand it, talk about it from the AC power.220 Volts AC Point has two lines, a 0 line, his voltage is always 0 volts, the other is the FireWire, the voltage is changing, a moment is
