In general, it is relatively simple to horizontally center a fixed-width block element, and we only need to set the width of the block element and set margin:0 Auto. However, for block elements that cannot be set to a fixed width, this trick does not work.Let me introduce the three commonly used methods to set the horizontal center of an indefinite wide block element.First: horizontal centering with float+relativeCSS code:. Wrap { float: left; position: relative; Left:50%;　　border: 1px solid red

In a distributed environment, managing a session typically uses the following three ways:First,session Replication mode management (that is, session replication)Summary: Copy the session data broadcast from one machine to the rest of the machine in the clusterusage Scenario : Fewer machines, less network trafficAdvantages : Simple implementation, less configuration, no impact on user access when a machine is down in the networkdisadvantage : Broadcast replication to the rest of the machine when
