/response, Then put a token that passes the verification in the user's session, and then the filter determines whether to allow response each time based on the token. This mode is divided: Keeper: filters or unified servlet. Authenticator: Use JAAS to implement it on the web. User qualification storage LDAP or database: 1. The Keeper intercepts and checks each protected resource. First, check whether this u

). As long as we still need to use PHP4, we must pay attention to the object transmission method. Some nuances may make you restless. For example, the following statement causes $ obj2 to become a copy of $ obj1. this is not surprising. $ Obj2 = $ obj1; The function will use the copy and return the copy, unless otherwise specified-we have to accept this situation. The following example causes many errors that are difficult to trace: Class ObjectKeeper { Var $ _ obj; // Whatever object is Fun

another saving-on technique. In PHP5, by default, an object reference is assigned or transferred (the reference is the object handle, not the object itself or a copy of the object ). As long as we still need to use PHP4, we must pay attention to the object transmission method. Some nuances may make you restless. For example, the following statement causes $ obj2 to become a copy of $ obj1. this is not surprising. $ Obj2 = $ obj1; The function will use the copy and return the copy, unless othe

House-keeping-sleep-time: the longest time for the house keeper to keep the thread in sleep state. house keeper is responsible for checking the status of each connection and determining whether to destroy or create the thread, the default value is 30 seconds.House-keeping-test-SQL: if an idle database connection is found. house keeper will use this statement for

I have been using jquery for a long time, but I have never studied it in depth. In the afternoon, I was very fascinated by the sharp jquery chapters 1st and 2nd.I have learned some jquery knowledge through the jquery manual before, but I have never seen the core of jquery systematically. after reading the first two chapters of jquery, jquery is very beautiful. simple, easy to understand, easy to use, and omnipotent$(Although a little exaggerated, haha). The write less, do more is my current unde

pool is depleted. Default:3Fatal-sql-exception: It is a comma-separated piece of information. When an SQL exception occurs, his exception information is compared to this fragment of information. If present in fragment, this exception will be considered a fatal error (Fatal SQL exception). In this case, the database connection will be discarded. No matter what happens, this exception is thrown back to the consumer. The user is best to configure a different exception to throw.Fatal-sql-exception-

mentioned above, this is generally called the aggregation between traditional telecom and enterprise application development. Bea wlcp provides developers with a group of industry-leading tools to program in common environments such as J2EE, Java, and Web services. By the time of writing this article, WLCP has two components: WebLogic SIP Server and WebLogic Network keeper, as shown in figure 2. Although this article focuses on WebLogic SIP Server, W

word RuntimeException. proxool comes with two implementations: 'org. logicalcobwebs. proxool. fatalSQLException 'and 'org. logicalcobwebs. proxool. fatalruntimeexception '. the latter is more suitable. House-keeping-sleep-time: The proxool automatically detects the time interval (in milliseconds) of each connection status. When idle connections are detected, the system immediately recycles them. The destruction time-out period is 30 seconds by default) The longest time for house

Recently, I encountered a connection pool leakage problem during development, so I learned something about the connection pool and sorted it out. Most of them were obtained online. Currently, the performance of the three mainstream connection pools is listed as follows: proxool> c3p0> DBCP. proxool also provides a visualized real-time monitoring tool for connection pools, which is stable and convenient, configuration is also very easy. Currently, spring development is widely used. Let's take a

-thrown to the consumer. It is best for the user to configure a different exception to throw.

Literally, zookeeper represents a zoo keeper, which is a fascinating name, and we think of the Hadoop ecosystem, where many of the projects ' logos are used by animals, such as the image of the elephant in Hadoop, So we can guess that Zookeep is doing some management work on these animals.I. Zookeeper BASIC INTRODUCTION 1.1 The zoo also needs to be safe.Zookeeper is a sub-project under Hadoop that coordinates some of the distributed frameworks associa

the calculation line of other details. However, once the forward propagation is complete, in the process of reverse propagation, the gate unit keeper finally obtains the gradient of the final output value of the entire network on its own output value. The chain rule states that the gate unit should multiply the return gradient by the local gradient of its input, resulting in a gradient of the output of the entire network to each input value of the ga

write an XML configuration mapping file to tell the framework if and when it is ORM. Also, once the object model has changed, the mapping file is modified. These have greatly increased the learning curve and workload of the developer and are prone to error. The idea of the Bean keeper is simple to do, and it simplifies these operations as much as possible. The Bean Keeper is an Open-source software based

The H.323 Protocol contains three signaling control channels: RAS signaling channel, call signaling channel, and H.245 control channel. The coordination of the three channels enables H.323 calls.The following section describes the components and channels of H.323: 3.1 components.H.323 defines four main components to construct a network-based communication system: Terminal, Gateway), network guard
