问题 I'm trying to set up server push with cloudflare, but they require multiple link header fields to push multiple files. However, I can't find any documented way to include multiple header fields with the same key in node.js. I tried providing an array, but that just concatenates them together as the value for a single header field. 回答1: express You pass an array of values to res.header('HeaderName', arrayOfValues) . Here's a working example and cURL output showing the duplicate response

问题 I have a little question like a title. How can i use ServerPush HTTP2 with PHP on IIS10? Many thank. 回答1: IIS only supports Push through the ASP.NET or similar. Also it does not support through HTTP Link Headers like many servers and CDNs do.

由 那年仲夏 提交于 2020-11-29 03:56:09
问题 Problem I am wondering how webpush protocol works? Does it keep some kind of connection open like WebSocket protocol? Or does it use mechanism similar to polling ?

How to implement Server push / long polling / comet using PHP and Javascript

由 假装没事ソ 提交于 2020-01-21 09:14:27
问题 How can I implement the comet / server push design pattern using PHP and Javascript? Essentially what I would like is something like this: User clicks a 'submit' button Javascript shows a message like 'Processing 0 / 100 items' Whenever a new item is processed, the php / server pushes out an update, and the javascript changes the message to 'Processing 2/100 items, 3/100 items, and so on'. How can I do this? Any links/info please? 回答1: Comet with PHP has some tricky issues with scaling. An

问题 I'm writing a basic push messaging system. A small change has caused it to stop workingly properly. Let me explain.

Session timeout when using signalr

由 蹲街弑〆低调 提交于 2020-01-03 17:32:14
问题 I have a web app that is used mainly for monitoring a system. It uses signalr to "server-push" updates from the server to refresh the display. The page also has some buttons which also uses the same signalr connection to send data to the server. The problem is signalr uses a separate connection so the session expires after the session timeout even when it is regularly sending and receiving data from the server. Is this the "correct" way to use signalr? Or should I just use signalr to inform

server push for millions of concurrent connections

由 主宰稳场 提交于 2020-01-02 03:23:06
问题 I am building a distributed system that consists of potentially millions of clients which all need to keep an open (preferrably HTTP) connection to wait for a command from the server (which is running somewhere else). The load of messages / commmands will not be very high, maybe one message / sec / 1000 clients which means it would be 1000 msg/sec @ 1 million clients. => it's basically about the concurrent connections. The requirements are simple too. One way messaging (server->client), only
