Cross-origin image load denied by Cross-Origin Resource Sharing policy
If you wish to load cross-origin images to a canvas, you need to either serve the image with cross-origin headers or under the same origin. That image under Facebook is served with the following header option set: Access-Control-Allow-Origin:* Meaning, it can be cross-origin loaded with the useCORS option. However, it would appear that your Host B isn't serving them with cross-origin headers set.

Blocked a frame with origin "https://www.facebook.com" from accessing a frame with origin "http://myapp.herokuapp.com"
Pretty old question, but it's still open- so In case you didn't see this answer already, Mademoiselle Geek is spot-on. A quick double-check on my heroku app verifies that you can, in fact, just type https: instead of http: and it will accept an SSL connection automatically- no set up required. The only thing you do have to set up is in your Facebook.js.coffee- this section.. initializeFacebookSDK = -> FB.init channelUrl : 'http://app.heroku.com/page/fbchannel' Change to.. initializeFacebookSDK = -> FB.init channelUrl : 'https://app.heroku.com/page/fbchannel' Then, depending on your operating system (I use linux) do a quick grep search (or search the text of files within a directory) for http://app.heroku and change it to https, just to be safe.

Not cross-domain. XMLHttpRequest cannot load localhost:portNo1 . Origin localhost:portNo2 is not allowed by Access-Control-Allow-Origin
Well, that's the problem. Cross-origin restrictions do not allow you to communicate across ports without sending a Access-Control-Allow-Origin: * header. A better solution would be to use Nginx or some other webserver to reverse proxy those two running applications to the same domain and port.

Cross Origin Request with Kohana and JavaScript
The Problem The problem I was having was due to a setting in my Apache config file which looked like this: <IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" </IfModule> In order to solve my particular problem I simple removed / commented out the above code as it was overriding the headers I sent from PHP. My implemented solution was then quite simple. In the following example we'll assume that I am making a call from one.example.com (the main website) to two.example.com (a sub-site). Kohana / PHP In my PHP I set the following headers, I've chosen to do this in my parent Controller. You could create your own Cors class or helper if you prefer. Basically you don't want to have this code duplicated hundreds of times throughout your project. $this->

IE10 and Cross-origin resource sharing (CORS) issues with Image / Canvas
Confirmed: IE10 does not support CORS images in an HTML 5 canvas. See RReverser's answer for a workaround. Edit Sorry, I haven't dealt with CORS images before and thought this question was about an AJAX request. According to Mozilla Developer Network you need to set image.crossOrigin to anonymous or use-credentials. Also, according to that page today, these attributes are not supported in IE, Safari, or Opera. This test was made to demonstrate that IE9 did not support it and it seems that same test still fails in IE10, so even if Safari and Opera have added support since the MDN article was written, it is quite possible that IE10 still lacks support. The only tip I can give you is that in general, allow-credentials is incompatible with a wildcard allow-origin. Either drop the allow-c

Two ASP.NET web applications - Cross origin request always succeeds without discretion
Cross-sub-domain requests are still considered cross-domain requests as different sub-domains can point to entirely different IPs and servers. You'll definitely get errors if you don't set up CORS properly in your production setup. Edit: To properly emulate production setup, you'll need to play with the IIS binding configuration. If you can't get it working, you shall try a VM for hosting the api.hybridwebapp.com, which will definitely work as CORS is triggered automatically between different servers.

SEC7118: XMLHttpRequest for /socket.io/1/?t=1370206038749 required Cross Origin Resource Sharing (CORS)
AFAIU, SEC7118 is not an error but just a notification. I've googled but didn't find the code reference on any MS site; anyway you can find 7118 messages when CORS works fine for IE10. This document focused on CORS and IE10 clarify what I mean (and it's definitely worth reading): http://blogs.msdn.com/b/ie/archive/2012/02/09/cors-for-xhr-in-ie10.aspx Anyway, I've found your issue when troubleshooting some sort of nodejs chat (actually, a BOSH backed js chat client) on IE10. In my case turned out that IE10 prepends "NS1:" to some xml attributes when sending requests, breaking things up. So, you should carefully check your xml payload looking for subtle differences (like the one we found) between IE10 and other (working) browsers. Hope this helps.

It is up to the server (facebook, google, etc) to allow their content to be loaded across domains. This is called Cross-Origin Resource Sharing. To enable CORS on your server, provide this header in your response: Access-Control-Allow-Origin: *. You cannot change the behavior of a server you do not own.

Disable firefox same origin policy
Let me answer my own question here, but any better answer is appreciated! A friend of mine told me that he thinks src code modification is needed in this case, unlike Chrome's --disable-web-security option. In particular, http://mxr.mozilla.org/mozilla-central/source/caps/src/nsScriptSecurityManager.cpp#536 might be the correct place to look at, but I haven't confirmed it myself. Anyways, I've figured another way to circumvent this problem in my research, it's not perfect but works. I'd still appreciate any insight that doesn't require recompiling FF, or confirmation that this is indeed the correct place to modify. Thanks all

Same origin policy and .ajax crossDomain
jQuery, being a pure JavaScript library, is bound by the exact same limitations and security measures as JavaScript. From the documentation: crossDomain (default: false for same-domain requests, true for cross-domain requests) Type: Boolean If you wish to force a crossDomain request (such as JSONP) on the same domain, set the value of crossDomain to true. This allows, for example, server-side redirection to another domain. In other words it can only force a non-cross-domain request to be considered cross-domain, but not the other way around. It has no effect when the request is actually cross-domain.

Circumventing the same-origin policy with DNS trickery
Practical answer (not recommended): Create CNAME records to the third-party domains from domains that you control, then use those domains and hope that the hosts of the third-party aren't looking at the HTTP Host header. Note that this wouldn't work if the clients attempt to authenticate the third-party hosts either; for example when using HTTPS (some client browsers may force the use of HTTPS in certain scenarios). Ideal answer: Ask the third-party to authorize requests made by code that came from your origin domain using CORS (some hosts already allow requests from code from any origin, you should check that). Alternative: If the third-party doesn't want to give clients the go-ahead to make cross-origin requests with code from your domain, then you have to make those requests your

How to enforce same origin policy in Express.js?
What can I do to prevent others from opening up a console and sending AJAX POST request Who is "others"? If others==users of the site... there is nothing you can do to stop them sending whatever requests they like, using the JavaScript console or any other means. You can't trust the client, so you have to have server-side authorisation: requiring that the user be logged into an account, and registering that the account has upvoted so can't vote again. If others==admins of other sites (by serving script to their users that causes submissions to your site)... it isn't possible for JavaScript on another site to cause an AJAX POST request, or at least not unless you deliberately opt into that using CORS. But it's quite possible for them to cause a POST by simply creating a <form>

How do I circumvent the same origin policy using JSONP and JQuery?
JSONP is, by its very nature, a GET, not a POST. It uses a script tag as its transport mechanism, and script tags GET their scripts. $.get 'http://two.com/', data: 'example' , dataType: 'jsonp' Also note that the server has to support JSONP for it to work, just like it would have to support (say) XML if you were requesting that. The format of what it sends back is specific to JSONP.

java script and same origin policy confusion
The Same-Origin policy doesn't have much to do with loading JavaScript. Regardless of where a script comes from, its actions take place under the aegis domain of the main page. Thus, if your main page comes from "domain1", then all scripts execute in the context of "domain1", whether they came from that domain or any other domain. Note that it's not possible to access the source code of a script that loads from some other domain. The reason your "dom1_normal" script reports "null" for that element reference is probably because you're importing the script before the <body>. The DOM is built incrementally, but scripts run synchronously when they're loaded, so if you call getElementById() for some element that's after the <script> tag, it won't be there.

Well, you are rather restricted in this case. If you're offline, then you need a database on the client. Normal browsers such as Chrome do not allow you do access the file system (think of the security implications if any website can access your file system). Thus, you really need a database to be running. Luckily, there's an HTML5 client based database option: http://blog.darkcrimson.com/2010/05/local-databases/

For those who only wish to retrieve information about places using the google maps API, which in the JSON provided by Google, I recommend using FourSquare's API instead, which allows cross-platform queries, something that Google Maps apparently does not.

Same origin policy response in Angular JS and Spring security OpenId Integration
You are sending a simple HTTP request to your openid authenticator(Either of Google,Yahoo,MyOpenID,Facebook etc.) Which on return provides you their page to enter your credentials or choose from your logged in accounts(in case of multiple accounts logged in). As soon as you enter your credentials or select your account to login, the request is redirected as a HTTPS request to the openid authenticator and that authenticator will authenticate you and return you your unique openid return url. In your case a simple HTTP request (http, your-website.com, 80) was raised from your angularjs application which was then redirected to a secure HTTPS request (https, your-website.com, 443) to authenticator, which turns out to be a "same origin policy" issue and you see a Response code 0.
