问题 In the comment by the link Jquery multiple Ajax Request in array loop the author said that making ajax requests in a loop may end up DDOS-ing ourselves. Does that apply only a loop or multiple ajax calls in general? I mean may the risk of DDOS-ing be as well if I make multiple ajax requests via recursive function like ajax(0); ajax(index) { var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function() { if(this.readyState == 4 && this.status == 200) { ajax(index+1) } }; xhr.open('POST',

问题 I'm having issues with Cypress loading the response body when I utilize the cy.request() command. In our application, when a form is filled out and submitted, it POSTs, and the response body is the new page. When I'm trying to do in Cypress is programmatically fill out the form.

问题 I'm sending chunked data from a NodeJS application back to the browser. The chunks are really json strings. Problem I'm having is that every time the onprogress function is called, it adds on a string of the complete data. Meaning that response chunk number two, is appended to response chunk number one, and so on. I'd like to get ONLY the "just now" received chunk. Here's the code: console.log("Start scan..."); var xhr = new XMLHttpRequest(); xhr.responseType = "text"; xhr.open("GET", "

问题 Suppose the page below is loaded from https://127.0.100.1 . The page makes an XMLHttpRequest to http://127.0.100.2 . This seems like mixed content : The page is loaded over a secure connection and a resource is loaded over an insecure connection. Mixed content should be blocked by the browser. Yet, the page below works just fine.* Why does it work: Why isn't the request blocked? Update: Going beyond the accepted answer, browsers can be configured to block mixed content for such addresses. *
