servlet sees that the value here is "keep-alive", or the request uses HTTP 1.1 (HTTP 1.1 performs a persistent connection by default), it can take advantage of the advantages of persistent connections, when a page contains multiple elements (such as an applet or image), the download time is significantly reduced. To achieve this, the servlet needs to send a Content-Length header in the response. The simple

php gets header information through the Fsockopen method, and if the request is a picture, the content-length here represents the size of the picture If you want to get the size of a remote picture, it's a common practice to get the contents of the remote picture back and then use strlen to compute the length, which requires downloading the pictures before you can compute them.
