keep alive php

First, keep-alive mode1. The HTTP protocol uses "request-answer" mode, when using normal mode, that is, non-keepalive mode , each request/reply client and server to create a new connection, immediately after the completion of the connection (the

What is Keep-alive? OverviewBy default, HTTP links are usually closed after the request is complete. This means that the server closes the TCP link after the delivery of the response has been completed. To keep the link open to satisfy multiple

During webpage development, keep-alive is an important attribute in HTTP. We all know that HTTP is built on TCP. In the early implementation of HTTP, each HTTP request must open a socket connection. This is very inefficient because many HTTP

Code used to determine the end of an HTTP request in the Keep-Alive mode. Therefore, you can determine the end of a request based on EOF. the following code (PHP) is very common: Copy the code as follows: $ fp is the handle while (!) produced by

Determine the end of an HTTP request in Keep-Alive mode. When a short connection is used, each HTTP request corresponds to a TCP connection. after the request is complete, the connection is immediately disconnected, and the server returns EOF.

When a short connection is used, each HTTP request corresponds to a TCP connection. after the request is complete, the connection is immediately disconnected, and the server returns EOF. Therefore, you can determine the end of a request based on EOF.

When a short connection is used, each HTTP request corresponds to a TCP connection. after the request is complete, the connection is immediately disconnected, and the server returns EOF. Therefore, you can determine the end of a request based on EOF.

When using short connection mode, each HTTP request corresponds to a TCP connection, the connection is immediately disconnected after the request completes, and the server returns EOF. So you can judge the end of a request based on EOF, the

Therefore, you can determine the end of a request based on EOF. The following code (PHP) is very common: Copy codeThe Code is as follows: // $ fp is the handle generated by fsockopen (). While (! Feof ($ fp )){ Echo fgets ($ fp ); } (Note: The short

So depending on the EOF to determine the end of a request, the following code (PHP) is common: Copy Code code as follows: $FP is the handle produced by Fsockopen () while (!feof ($fp)) { Echo fgets ($FP); } (Note: The
