Each process can only maintain one connection at a certain time, and is efficient, but has a large memory footprint. This

Why do you have a working mode? More efficient support of different platforms, better for the special requirements of the site customization. For example, sites that require more scalability can choose to use a thread's MPM, worker or a event site that requires reliability or is compatible with older software prefork . How many working modes are there? Perfork Process handles each reque

I. IntroductionWin32 API provides us with an efficient way to perform file operations, that is, memory ing files. The memory ing file allows us to reserve a memory area in the virtual address space of the Win32 process and map the target file to the virtual memory. We can directly operate the data in the file by accessing the memory data, as if the data was stored in the memory. In fact, we do not and do not need to call API functions to read and write files, and we do not need to provide any ca
