Security and Cross Domain with ASP.NET MVC JsonResult and jQuery

阅读更多关于 Security and Cross Domain with ASP.NET MVC JsonResult and jQuery

问题 I am using asp.net MVC to develop an application that will have ajax interactions. I have JsonResult methods in the controller returning my json serialized data. So for example when a request is made to http://somesite.com/findwidgets/ mvc serializes the data as json and sends it back. I am using jQuery on the client side to handle the ajax requests and to then manipulate the results. I am not having any trouble getting the data but i have found that i can make requests to http://somesite.com

Multiple Iframes sending ONE request to the same SRC

阅读更多关于 Multiple Iframes sending ONE request to the same SRC

问题 I was wondering if there was a way to have say 3 iframes load the same resource (http://myservice.php) with ONLY ONE request from the iframe. The myservice.php returns an Html Document and the browser should somehow load the html without reloading everything 2 additional times including CSS and JS in the loaded HTML document. In other words, is it possible with ONLY 1 request sent from the 1st iframe to load the HTML document from myservice.php, and have the other 2 iframes load the same html

Making a HTTP request to Azure mobile services from asp.net web site

问题 NET web site and a mobile service on azure. They're not on the same domains and hence i get the following error: Failed to load resource: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin is therefore not allowed access. However, I edited the web config file as recommended in this article: http://encosia.com/using-cors-to-access-asp-net-services-across-domains/ and I added: <system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow

Apigee OPTIONS 404

阅读更多关于 Apigee OPTIONS 404

问题 I have been stumped by Apigee's CORS support. I setup a new proxy and made sure to tick the " Enable Direct Browser Access for Your API — Allow direct requests from a browser via CORS." box. It appears that CORS is working for the normal GET requests, however pre-flight OPTIONS requests are not found and are returning a 404. I found this answer but was not able to resolve my problem because it seems like a different problem perhaps? The main question I would like answered is how do I setup

How to close an authentication pop up window having a cross-domain url?

阅读更多关于 How to close an authentication pop up window having a cross-domain url?

问题 I was following the accepted answer for this question How do I get around window.opener cross-domain security to solve my problem. The code works great but fails at one use case where instead of the pop up window url getting changed from some other domain to your own domain, it simply redirects on its own domain just like sometime if you try to authenticate a third paty app on facebook or some other social network, it simply redirects on its own as you have already authenticated earlier. How
