查看squid日志状态全是TCP_HIT,全被磁盘缓存住了,没有缓存到内存里面.查看了下squid的默认配置文件才发现 maximum_object_size_in_memory 8 KB 原来squid默认只会把小于8 KB的文件缓存到内存中.du命令看了下shufa.jpg有100K. 把此参数修改后全TCP_MEM_HIT了...^^ 192.168.10.139 - - [15/Dec/2011:17:13...
TCP_MISS- Object not found in cache, downloaded from the OCS. TCP_HIT- Object found in cache. TCP_NC_MISS- The request was made for an object that can't be cached. TCP_REFRESH_MISS- Appliance had the object in cache, but a check with the OCS (GET with the If-modified-since...
Istill have minimum_object_size to 0 and a large enoughmaximum_object_size for this to be in memory. In fact the object is inmemory as clients that don't send IMS requests do get the object via aTCP_MEM_HIT. Is there some reason why IMS requests are not answered frommemory ? Thanks...
Through this overview on TCP socket communication, I have shown what TCP sockets are, what they're used for and the complete flow of a TCP socket communication between one TCP socket server and a TCP socket client. I have also presented a practical example, so the reader can learn all con...
TCP_NEGATIVE_HIT The request was for a negatively-cached object. Negative-caching refers to caching certain types of errors, such as "404 Not Found." The amount of time these errors are cached is controlled with the negative_ttl configuration parameter. ...

TCP握手协议 在TCP/IP协议中,TCP协议提供可靠的连接服务,采用三次握手建立一个连接. 第一次握手:建立连接时,客户端发送syn包(syn=j)到服务器,并进入SYN_SEND状态,等待服务器确认; SYN:同步序列编号(Synchronize Sequence Numbers) 第二次握手:服务器收到syn包,必须确认客户的SYN(ack=j+1),同时自己也发送一个...
