I'm looking for details on the DEBUG HTTP verb. It's clear to me that this is used for remote debugging - though I'm not even sure if it's for IIS or ASP.NET... If I want to access this interface directly - i.e. not through Visual Studio, but sending these commands manually - what do I need to know? What are the commands for it? I'm a...
I'm writing a Java client application to receive live M-JPEG video from an IP camera. The video is sent by the camera as an endless multipart HTTP message where each part is a single JPEG frame. I need to process each of these frames as they arrive, so I'm hoping there's a way to make an HTTP request that asynchronously triggers an event...
For a POST method, the W3 specs say: If a resource has been created on the origin server, the response SHOULD be 201 (Created) and contain an entity which describes the status of the request and refers to the new resource, and a Location header (see Section 10.4). http://www.ietf.org/internet-drafts/draft-ietf-httpbi...
Hi, I need to screen scrape some data from a website, because it isn't available via their web service. When I've needed to do this previously, I've written the Java code myself using Apache's HTTP client library to make the relevant HTTP calls to download the data. I figured out the relevant calls I needed to make by clicking through t...
If webserver can send gzip response, why can't browser sent gzip request? ...
I am trying to write a C# http server for a personal project, i am wondering how i can change the returned server header from Microsoft-HTTPAPI/2.0, to something else? public class HttpWebServer { private HttpListener Listener; public void Start() { Listener = new HttpListener(); Lis...
I have a python application that relies on a file that is downloaded by a client from a website. The website is not under my control and has no API to check for a "latest version" of the file. Is there a simple way to access the file (in python) via a URL and check it's date (or size) without having to download it to the clients machin...
I'm trying to figure out if it's possible to slow down the server when it's sending multipart/xmixed-replace responses. I want my client to try to rate limit a motion jpeg stream. I've found a lot of documentation about what the server sends in an HTTP response but nothing about what the client sends. What does the client send, if any...
My Flex UI is communicating with a local HTTP server through a REST-inspired API. I want to be able to use HTTP's put, delete and head methods as part of the API. Currently, whenever I use mx.rpc.http.HTTPService and set the method to something other than get or post, the server only sees a get. The Adobe docs for HTTPService say: Yo...
As an addition to my previous post on Creating a web server in pure C, I'm having some trouble with the Sending function. Here's two code snippets: int Send(char *message) { int length, bytes_sent; length = strlen(message); bytes_sent = send(connecting_socket, message, length, 0); return bytes_sent; } ...
I'm following along with this useful looking answer to my question. It seems to be working, but here are two questions I have: How do I detect an HTTP error? The didFailWithError method doesn't seem to be getting called? UPDATE: It considers any response a success. So I guess I have to handle HTTP errors in the didRecieveResponse m...
An HTTP GET query string is a ordered sequence of key/value pairs: ?spam=eggs&spam=ham&foo=bar Is, with certain semantics, equivalent to the following dictionary: {'spam': ['eggs', 'ham'], 'foo': bar} This happens to work well for boolean properties of that page being requested: ?expand=1&expand=2&highlight=7&highlight=9 {'expand'...
I've been thinking about batch reads and writes in a RESTful environment, and I think I've come to the realization that I have broader questions about HTTP caching. (Below I use commas (",") to delimit multiple record IDs, but that detail is not particular to the discussion.) I started with this problem: 1. Single GET invalidated by b...
See, for example, §13.3.3 and §13.3.4. It doesn't seem to me that this could be related to "media range" (§14.1, e.g. Accept: text/*), nor "language range" (§14.4, e.g. Accept-Language: da, en-gb;q=0.8, en;q=0.7). Maybe it's the "accept range" (§14.5), which puts byte limitations on a response? If that's true, how do ETags relate? ...
In Java I can write a really basic JSP index.jsp like so: <% request.getRequestDispatcher("/home.action").forward(request, response); %> The effect of this is that a user requesting index.jsp (or just the containing directory assuming index.jsp is a default document for the directory) will see home.action without a browser redirect, i....
How can I make a PHP script cache-friendly to our private reverse proxy (Squid)? I would like it to stay cached for the rest of the day. In other words, the page's last modification is 00:00 today and it will expire at 00:00 tomorrow. What are the minimum required HTTP headers to do this reliably? EDIT: I do not want the client's bro...
I was wondering if search engines respect the HTTP header field Content-Location. This could be useful e.g. when you want to remove the session id argument out of the URL: GET /foo/bar?sid=0123456789 HTTP/1.1 Host: example.com … HTTP/1.1 200 OK Content-Location: http://example.com/foo/bar … Clarification: I dont’t want to redirect...
I'm prototyping a realtime notification mechanism using http over port 80. The aim of the project is to allow a Flash application to respond to an event on a remote server quickly (specifically an inbound phone call being connected to a phone next to the computer.) Polling is one approach, but is too slow. Currently I use a socket connec...
What's a good way to connect the synchronous http request/response model with an asynchronous queue based model? When the user's HTTP request comes it generates a work request that goes onto a queue (beanstalkd in this case). One of the workers picks up the request, does the work, and prepares a response. The queue model is not request...
I have: Request request = new Request(Method.GET, "https://www.awebsite.com/login"); Client client = new Client(Protocol.HTTPS); Response response = client.handle(request); ... response.getEntity().write(System.out); But I don't know how to set the login parameters... I want code that does the escaping etc can switch between get/po...
