This article will share with you the code and usage of the php tool for implementing Web page caching. it is very practical and can be referenced by other users who need it. When php programs defend against high-traffic access, dynamic websites are often difficult to attract. Therefore, the cache mechanism should be introduced. Generally, there are two types of cache. I. file cache II. cache data query results and use memory for high-speed caching In this example, file caching is used. The main

Php implements tool class sharing for web page caching, and php web page caching tool class. Php implements tool-type sharing for web cache. php tool-type php programs are often difficult to attract dynamic websites when they resist high-traffic access. Therefore, the cache mechanism should be introduced, in general, php implements tool-class sharing for web page caching, and php web page caching tool-class When php programs defend against high-traffic access, dynamic websites are often difficu

Frankfei at 2007/08/01 Objectbuilder provides many policies and can even be expanded as needed. How can we use the provided policies correctly? This articleArticleI will first introduce singletonpolicy. In our actual project development, we often encounter the situation of creating the same class multiple times. If we use the general method to create a new class, every time we create a new class, an instance is generated, and there is no problem with small systems, but when the system

['passwd'];Echo date ('Y m d H: I: S', $ _ SESSION ['Time']);Echo'Back to the previous page ';?>2.3 session_id ([string $ id]): Get and/or set the current session idIn php5, you can use session_id () or get the session_id and session_name of the current session by the SID appended to the url.If session_id () has a specific value (that is, the $ id parameter is specified), the current session_id value will be replaced. Before using this function, you must start the session: session_start ();Exam

PHP Implements Web caching tool class sharing, PHP Web caching tool class When the PHP program is resistant to high-traffic access, dynamic sites are often difficult to parry, so introduce a caching mechanism that typically has two types of caches First, the file cache Second, the data query result cache, using memory to implement the cache This example uses the file cache primarily. The main principle is to use a cache function to store the results of a Web page, and if called again in a speci

1. Tomcat's optimization experienceA: Remove the watch for Web. XML and edit the JSP into a servlet in advance.With surplus physical memory, increase the memory of the JVM used by Tomcat2. The difference between the get and post methods of HTTP requestsA: The servlet has a good definition of lifetime, including loading and instantiation, initialization, processing requests, and end of service. This lifetime

Java Basics-Stack and heap, static, final modifier, inner class, and Java memory allocation (RPM)Java Stack and heapHeap: Random in orderStack: LIFO (last-in/first-out).The Java heap is a run-time data area in which the objects of the class allocate space. These objects are established through directives such as new, NewArray, Anewarray, and Multianewarray, and they do not require program code to be explicitly released. Heap is responsible for garbage collection, the advantage of the heap is the

Document directory HTTP Channel TCP Channel Introduction Microsoft. NET Remoting provides a framework that allows an object to interact with another object through an application domain. This framework provides a variety of services, including activation and storage support, and communication channels responsible for message transmission with remote applications. The formatter is used to encode and decode a message before it is transmitted through a channel. Applications can use binary encod

A cookie class is provided in the Java servlet with two parameters representing the name and value of the cookie, respectively. The cookie class provides various methods for setting the cookie's properties, such as the Setmaxage () method to set the cookie's lifetime. If the

join rows. Next, it creates an execution plan based on the compiled plan. This execution plan contains instructions with all logical references translated to actual objects, and tracking mechanism s for query execution. Finally, the server starts execution from the top of the instruction tree. Creating A compiled plan is expensive because the server needs to find the optimal plan out of hundreds of potential Candi Dates. Distinguishing between compile and execution helps overall server performa
