the current network situation.　　The decision to direct the user's request to a node cache server that is relatively light on the user's last load.　　Through the combination of user location algorithm and server health detection algorithm, the user's request can be directed to a cache server distributed on the edge of the network to ensure the user's access can be more timely and reliable response. Since a large number of user accesses are directly res

, etc.), mainly using a piece of embedded JS Code, the essence of the method is the same as the commercial-level products, considering the performance and independence, this article uses the latter method. 2. Add two sections of js code to the SharePoint page to be counted. One section of JS is used to obtain information about the currently logged-on user, and the other section is used to record

Php restricts access to ip segments, prohibits code sharing of ip submission forms, and ip forms. In php, you can restrict access to ip segments and prohibit code sharing in the ip address submission form. you can add the following code on the page where you want to prohibit

AddIP (ipAddress, ipSrc, ipDatetime ); // Obtain the page accessed by the userString pageurl = Request. Url. ToString ();// Determine whether the access is a response pageIf (pageurl. EndsWith ("IPStat. aspx ")){// Lock the variableApplication. Lock ();//

Sometimes you need to control access based on IP addresses to restrict or guide certain access requests. For example, allow normal access from visitors in the LAN segment, but prohibit access from the Internet. Mango briefly introduces how to use PHP scripts to implement this function. Assume that the IP address range

This feature prevents the theft and decryption of verification codes and prevents unwanted malicious attacks and hacks.Ideas are as follows:Validating

1. The question was raised When designing small and medium Web applications, you can choose the Microsoft Accesss as the database. Frequent additions and deletions are made during the use of the database. In fact, Microsoft Access does not effectively release allocated but deleted object space, which means that even if you delete an object, the object still occupies the space of the database, making the database bigger and larger. Not only occupy unn

Document directory Preface 1. Multithreading 2. Access Controls Conclusion Preface In many cases, we use multiple threads. When using multiple threads, we often access controls, which can cause many problems !!! I will give you an example that is the most common and frequently used. While improving your skills, I hope it will bring you some convenience. If there is something wrong, please leave a mess

queue or try again. After all the written cache data is pushed into the cache pool, the queue retains all the tasks that update the cache, and does not block the main process, that is, the main process accessed by the user is not blocked. They only read the data in the cache pool and do not care about the validity period. Reading data will not be affected if the database crashes. The concept of concurrency can be viewed at a relative time. The computer will handle it on its own, and you don't

instantaneous concurrency generally will not cause any practical problems. So how to solve this problem from the code level depends on how you design the system. Second-level cache. Put the data in a key that has a longer expiration time. When the avalanche lock, ensure that only one PHP process access to the database, the rest of the see Lock is no longer accessible, directly return the data in the cache

Visit | speed | website | optimization First, do not put the entire page into a table Generally, we are using a table layout, the entire content of the page into a table (table), and then by the cell TD to divide the layout of each "block", the display speed of this site is absolutely slow. Because the table to wait for all the contents are loaded after the display, if some content is inaccessible, it will delay the entire page access speed. In the la
