C# - Use JQuery To Retrieve Single Value From Another Domain?
Apr 21, 2010
I'm doing some work for a charity that's having a fund drive. Whenever someone makes a pledge, their pledge amount is logged to SQL Server. They'd like to have the pledge total posted across a couple of other websites, so I thought, "a-ha! this is an opportune time to learn about web services!" I assumed I could set up a web service that returns the pledge total as a string, and then dump some jquery code on the external sites that would call the web service.
It's about nine hours later, and I'm still trying to figure this stuff out. It sounds like JSONP is the only way to do cross-domain requests, but even after reviewing a bunch of tutorials, I'm not sure how to make my .NET page return the right value, and now I'm wondering if there isn't a better way of doing this altogether. Can anyone provide a totally simplified code sample?
TL;DR: I need to return a single value to a bunch of pages using jquery or javascript from another web server.

i am working on a project that you can subscribe with your company name and you can use all features of site specificly to your company. for example company abcd can get its own url from our website like
www.test.com/abcd/productlist.aspx
company efgh can also login with its own url and see its product list.
www.test.com/efgh/productlist.aspx
I am thinking on the approach that will use Global.ascx file to distinguish companies, i will write code to extract company name from url in global.ascx for every valid request and in all the pages i will put this.form.action = request.rawurl.

We are having a project which is for various online application systems for an educational institute. (Asp.Net 2.0 Web Site)
initially we developed all applications in single project with proper folder structure. but now we want to make each application as separate product.
all applications share single authentication(Obviusly this is single project) want to keep that way only.
I want to split project in smaller projects but want to keep shared authentication so how should i orgnise this project in IDE.
Also i need guidence on hosting such project
i should make small projects within single solution file. and at the time of publish amke single virtual directory to host the root project(login.aspx etc) and in subdirectories i should host other projects. so this way SSO(single sign on) across applications is possible ..

I have a Single Sign-on solution which is working great in our test environment. It uses Cross-Sub-Domain cookies to share the authentication ticket between 2 web applications. Sign-on is done only on one of the applications and on the second site the user is authenticated by the cookie created by the first site.The problem is that when I roll it into the production environment the single sign-on no longer works. I'm looking for any ideas on why this might be. More details below:1) Both apps are implemented using ASP.NET MVC2

How can I use a Guid for implementing single sign on the same domain? I can't use sessions as the different web apps would open in new windows hence loosing the session.
Technology used: ASP.net 3.5, MVC2 architecture, C#.

After the up gradation process (ASP.NET 2.0 to 4.0),We didn't run all three applications in same times and also form authentication crossed.

i want to have several domains A, B, C where a user can enter his username and password to login to a common main domain D.
So the user goes to A, B or C, enters his username and password, clicks the "login" button, and is then on the main domain D in a logged in/authenticated state. Then the user does the things he wants to do, and then clicks the logout-button and is then returned to the original domain that he came from, be it A, B or C.
What is the best way to do this?
I currently use forms authentication in ASP.NET 4.0 (C#).

In the following code, I need to modify the Handler so that the records or results that display are based on a QueryString value. Currently all of the records in the table display on the page but I want records to display based on the passing a querystring value based on the field, id. I have tried to alter the code without much success.
Public Class FileVB : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim id As Integer = Integer.Parse(context.Request.QueryString("id"))
Dim bytes As Byte()
Dim contentType As String
Dim strConnString As String = ConfigurationManager.ConnectionStrings("fitnesConnectionString").ConnectionString
Dim name As String

I am trying out jsonp with jQuery. I found many examples on the web and I believe my code is correct, but its still not working for me.
My web service:
using System.Web;
using System.Web.Script.Services;
using System.Web.Services;
using System.Web.Script.Serialization;..........
Firebug shows this is a success, but I am getting null from the alert. I have my webservice in iis7 locally and I am testing through my debug in my client project.
I need to get cross-domain working.

This is a followup question to the one here
Here's briefly what I am trying to do. The File server creates a text file to indicate an end of the process. On a webpage on the Web Server, I loop every x seconds and make an ajax request to find out if the test file exists (ajax request to [URL]
I've tried the following approaches so far:
Trigger a web method from the client side that creates a HttpContext object to verify if the text file exists. But this is too strenous on the server and I started getting all kinds of exceptions in the Event Viewer.

I'm building a greasemonkey script to make posting to craigslist a lot easier for our clients.
Basically the flow is this:
User logs into our system (established authentication cookies with asp.net)User navigates to a section on our site called "CraigsList". If they have the greasemonkey script installed it automatically opens up craigslist in a new tab.
The greasemonkey script then does a request back to our site at [URL] to retrieve a list of available items to be posted to craigslist.
This is where it fails because the request to [URL] is not including any of the authentication cookies. I'm not sure if it doesn't include the cookies because the request originates from [URL] and not [URL] or what. I know it's an authentication issue because looking at it in fiddler it returns a 302 and redirects to the login page.
Here is my request:

I have this polling script to check if a text file is created on the server. Works great locally, but fails when the file is on a different domain. How would i rewrite this for cross domain support?
$.ajax({
url: 'http://blah.mydomain.com/test.txt',
type: "GET",
success: function(result) {
//Success!
window.location.replace(Successful.aspx');
},
error: function(request, status, error) {
setTimeout("VerifyStatus(" + pollingInterval + ")");
}
});
EDIT: I ended up using YQL to solve the cross domain issue and although it works, YQL is really slow that's adding quite a bit of performance overhead. Can anyone suggest a better solution for cross domain JQuery calls?

I have a simple script making a request to the server:
var DTO = { 'path': path };
var url = 'default.aspx/Get';
var test;
$('#getInstance').click(function () {
$.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(DTO),
contentType: 'application/json; charset=utf-8',
success: function (msg) {
test = msg;
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
});
This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static MyObject Get(string path)
{
MyObject foo = new MyObject();
return foo;
}
Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]
Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?
