This solves the problem that the CGI process mode consumes too much, and utilizes the advantage that the CGI process mode has no thread security problem.Therefore, if you are using ISAPI to run PHP you must use the thread safe version, while running PHP in fastcgi mode does

C # implement HTTP protocol: multi-thread file transmission

Many people have experienced the use of network ant financial or network express files on the Internet. The use of these software can greatly speed up the transmission of files on the Internet and reduce the time for file transmission. Why are these software so powerful? The main reason is that these software uses multi‑thread download and resumable data transfer. If we compile a program like this and can q

[Concurrent parallel]_[c/c++]_[uses thread-local storage threads locally Storage (TLS) calls to copy a file interface case]

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visi
