I have one question
suppose in each http request there is "cache-control:max-age=0 in http request",so each request will go all the way to origin web server. Does it mean CDN is not usefuly anymore if the request is this?
How can I capture data send to a webserver/website?
Try Fiddler. It acts as a system-wide proxy and captures all http requests and provides a way to inspect them.
Which Http error/status code is the appropriate?
Both scenarios that you described are server errors. Regardless if it was a DB operation that fails or you server-side code didn't handle an error (unhandled error). Therefore, for the Front-end point of view, A server error has occurred (500 error status). Now, differentiating an custom application error from an...
Why I got so many connection events on Node's HTTP server?
javascript,node.js,http,websocket,socket.io
The connections you're logging from the HTTP server are to be expected and are related to the resources that are being used on your HTML pages (JS, CSS, images, favicon, etc). The port numbers you're logging are the client side port numbers. While not random, they will change for every...
Server initiated requests
Before websockets we had polling. This literally means having the client periodically (every few seconds, or whatever time period makes sense for your application), make a request to the server to find out the status of the job. An optimization many people use is "long" polling. This involves having the...

nodejs head request isn't triggering events
The problem is that you don't declare a data or readable event handler. According to the fine manual: A Readable stream will not start emitting data until you indicate that you are ready to receive it. Instead, the stream will be put in a "paused" state indefinitely (until you start...
Python exception for HTTP response codes
The built-in Python exceptions are probably not a good fit for what you are doing. You will want to subclass the base class Exception, and throw your own custom exceptions based on each scenario you want to communicate. A good example is how the Python Requests HTTP library defines its...
What does `expires -1` mean in NGINX `location` directive?
If expires -1 is used, it means that these pages are never cached. The expire directive instructs the browser to expire file cache after a certain amount of time (or at a certain time). If a negative value is given, there is no caching.
Does Ruby support nonblocking HTTP requests without a third-party library?
ruby,http,asynchronous,gem,eventmachine
Based on my tests, MRI does support nonblocking HTTP requests simply by using a thread. Threads don't always allow parallelism in Ruby due to the GIL, but net/http appears to be one of the exceptions: require 'net/http' require 'benchmark' uri = URI('http://stackoverflow.com/questions/30899019/') n = 10 Benchmark.bm do |b| b.report {...
Can the HTTP method “PATCH” be safely used across proxies etc.?
http,caching,filter,proxy,http-patch
The answer to this question is a moving target. As time progresses and PATCH either becomes more or less popular, the systems in the network may or may not support it. Generally only the network entities that will care about HTTP verbs will be OSI Level 3 (IP) and up...
request.headers['HTTP_AUTH_TOKEN'] does not work for https server
It turns out that I need to use key HTTP_X_AUTH_TOKEN in order to get the value. And I also need to prepend X- to all my custom headers, otherwise the web server won't be able to recognize the custom headers.
AngularJS $http request using forEach inside of Controller
You are trying to log $scope.infos without waiting until requests complete and push loaded response data to array. The answer here is using Promises for providing callback to fire once all requests resolve and push their respective data: app.controller('mainController', function($scope, $http, $q) { var url = 'https://api.twitch.tv/kraken/channels/'; $scope.channels = ["freecodecamp",...

ASP.net MVC HTTP Request error with payload
You need to move the data to the Request Body. In Fiddler it would be a separate input box (below the one in your screenshot). Your Headers for POST http://localhost:53660/api/pooltests become: User-Agent: Fiddler Host: localhost:53660 Content-Type: application/json Content-Length: 140 The headers Content-Type should be application/json and the Content-Length will be...
In simple RESTful design, does PATCH imply mapping to CRUD's (ORM's) “update” and PUT to “destroy”+“create” (to replace a resource)?
Well, Both the actions actually means update, where PUT is full update and PATCH is partial update. In case of PUT you already know the identifier of the resource and the resource already exists, so it is not a create and delete action per se. Infact, you can make do...
Headers for security
You definitely don't want to put them in HTML using <meta> tags, as JavaScript can just remove them, and (correct) browsers will ignore them. You need to set them as HTTP response headers on the server, and this depends on your server / framework. You also don't want to do...
Mule: Migrating to the New HTTP Connector
The solution is: wrap your element into a processor-chain As follows: <processor-chain> <cxf:jaxws-client serviceClass="com.acme.orders.v2_0.IOrderServiceBean" port="OrderServiceBean_v2_0Port" operation="getApprovedOrderOp" /> <http:request config-ref="http.request.config" path="acme-services/OrderServiceBean_v2_0" method="POST" /> </processor-chain> This is because cxf is intercepting, so after the processor chain you would have the same object as you had in your previous solution....
Custom HTTP Header or cookies? how custom authentication/authorization helps in CSRF?

Browser will always blindly add cookie to every request. When authentication is based, for instance, on bearer...
Android Java Http Request Post
The first problem may be that you didn't add the INTERNET permission in your AndroidManifest.xml. To resolve this just add this line <uses-permission android:name="android.permission.INTERNET" /> in your manifest. The other problem is that you're trying to execute a post request on main thread. It causes NetworkOnMainThreadException. You should use AsyncTask...
Which LiftResponse class is appropriate for returning an XML based file format?
JsonResponse and PlainTextResponse are helpers that ultimately return an InMemoryResponse. You can see the source code here and here respectively. You will notice that PlainTextResponse sets a mimetype of "text/html" which is not necessarily correct for XML. There is also an XmlResponse type that you can investigate here and which...

Handling POST request via Socket in Java

How to return value in Meteor.JS from HTTP.call “GET”
javascript,ajax,http,meteor,facebook-javascript-sdk
Don't pass a callback to get the HTTP to return.

Purpose of Pseudo/Colon Header Fields
http,networking,http-headers,protocols,http2
The purpose of the pseudo header fields was to unify the way the request/response information was carried in SPDY and later in HTTP/2 (which is based on SPDY). When SPDY was designed (but also HTTP/2) there was a need to transport request or response information that is formatted in different...
Python - sending http requests as strings
Assuming python 3, it is recommended that you use urllib.request. But since you specifically ask for providing the HTTP message as a string, I assume you want to do low level stuff, so you can also use http.client: import http.client connection = http.client.HTTPConnection('www.python.org') connection.request('GET', '/') response = connection.getresponse() print(response.status) print(response.msg)...
Idempotent PUT in a concurrent environment
Idempotency means that in an isolated environment multiple requests from a same client does not have any effect on the state of resource. If request from another client changes the state of the resource, than it does not break the idempotency principle. Although, if you really want to ensure that...

So, it wasn't a problem with either Docker or Elastic.

$http headers is not a function - angularjs
As Andy said already, headers is the 3rd parameter of the success callback. So you will have to do this:- success(function(data, status, headers, config) { // this callback will be called asynchronously // when the response is available }) I wasn't going to add this as an answer but doing...

Can I submit a form with google's recaptcha in it from my app?
