An application pool is a container that server allocates memory to a dynamic Web site, and multiple dynamic sites can exist in the same application pool. If there are too many dynamic sites, which can cause memory-level overflow vulnerabilities that affect all dynamic Web sites on that application pool, if the program pool does not limit its use of memory, it will have an impact on sites that use other program pools, because the server has a certain s

The Python standard library provides us with the threading and multiprocessing modules to write the corresponding multithreaded/multi-process code, but when the project reaches a certain scale, frequent creation/destruction of processes or threads is very resource-intensive, At this point we are going to write our own pool of threads/processes to change the time in space. But starting with Python3.2, the standard library provides us with the Concurrent.futures module, which provides Threadpoolex

Keywords:Enterprise Applications The customer said today that he wants to add a watermark to the image he uploaded to prevent others from stealing the image. He thinks that his images are very important. So...Well, if the customer has a need, we can satisfy him. I used to write less image operations APIs, so I have never touched on the Image Watermarking function, but for the current network. These are nothing at all. I searched the internet and found

Threadpoolexecutor class in JavaThe Java.uitl.concurrent.ThreadPoolExecutor class is the most core class in the thread pool, so if you want a thorough understanding of the thread pools in Java, you must first understand this class. Let's look at the specific implementation of the Threadpoolexecutor class source.Four construction methods are provided in the Threadpoolexecutor class:As you can te
