loopback message;0 represents a loopback response message.Code: 0． Check code:The 16-bit data (starting with the ICMP type) is reversed and fetched instead. To calculate the checksum code, the checksum Code field should be zero. These zeros will be replaced by the checksum code in the future.． Identifiers: If code = 0, the code that helps match the loopback and echo response can be 0.． Sequence code: If the code = 0, the sequence code that helps match the loopback and echo response can be 0.． D

An SSL certificate is a digital certificate that uses the secure Socket Layer protocol to establish a secure channel between the browser and the WEB server to achieve:1, the data information between the client and the server encrypted transmission, to ensure the security of the transmission of information between the parties, can not be intercepted by third parties;2. The user can verify that the website he visited is true and reliable through the server certificate.I. Introduction to the Enviro

The following is a test of the distributed cache memcached software. I have been learning how to implement the cache of a Large-traffic website. I have read the memcached documents and have no time to test it, this article tests the distributed cache memcached environment as follows: (two computers serve as servers)First:CPU: inter (r) Pentium (r) 4 CPU 2.8gMemory: 1 GBSystem: Windows 7IIS: IIS 7IP: 172.10.1.97Environment: LocalInstall: memcached 1.2.
