Squid reverse proxy CDN build configuration Because of the company's business needs, you need to build a cdn node somewhere by yourself. You can build a node by using DNSpod smart resolution and squid. Installation path:/usr/local/squid 1.

command. This command only accepts internal requests, that is, requests forwarded by the backend. In the backend view logic, you must explicitly write the headers information X-Accel-Redirect. The pseudocode is as follows: location /upload/(.*) { alias /vagrant/; internal;}@app.router('upload/ After such processing, you can redirect static resources. This is a common practice. Many download servers can use this method to Download user permissions.

Php nginx is a simple implementation method for real-time output. The method for enabling real-time output in PHP is ob_implicit_flush (), However, it does not work in most cases, In the php. ini configuration, most output_buffering output buffering is enabled On, Zlib. output_compression is also frequently enabled, In addition to the PHP layer, Nginx buffer settings proxy_buffering and gzip compression are also enabled. For the sake of one or two pages, I am afraid no one will make this c
