HTTP协议是纯客户端服务器协议.客户端发送请求，HTTP服务器响应.每次上传文件时，客户端都会使用POST方法发送请求，该方法包含一些数据，包括一个或多个文件的内容. HTTP服务器接收此数据.每个这样的请求都使用单独的服务器端脚本处理，该脚本执行发布的所有副作用，通常，该请求读取/分析发布的文件的内容，并将数据添加到数据库中.这里是引入增量计数器的地方，也是增加它的时间.

HTTP protocol is a pure client-server protocol. A client sends a request, an HTTP server responds back. Every time a file is uploaded, a client sends request with the method POST which contains some data, including content of one or more files. HTTP server receives this data. Each such request it processed with a separate server-side scripts which performs all the side effect of the post, typically, reads/analyzes the content of the posted file(s) and adds data to database. This is the place to introduce increment counter and the time to increment it.
