Can Flash Load Static .JPG Files Without Crossdomain.xml Policies
Dec 7, 2010
I'm doing a Flash Banner for an ADv campaing. Since the max swf file size allowed is very low, I'm trying to load external JPG images from the main server.Reading the crossdomain policies for Flash movies I see that:You cannot load variables or XML data into a Flash movie from another domain.
It's the same with static files as Jpg images?I'm testing the banner with various results: looking in Firebug, images are always loaded, but sometimes they appear, sometimes not, sometimes only the first time (it's a loop). There are no warnings however.
Loading the Banner with the same domain as the static images always works.I also tried to put a crossdomain.xml file on the domain that serves the static images, but problem seems to continue (maybe Flash cache that request somewhere..

I want to create flash banner with XML content, and host it on my site with crossdomain.xml, and then share banner code with other sites for banner exchange.So, everything is on my server.Will loading banner, on other sites, load XML from my server, if both banner and XML resides on the same server, but banner is loaded on the other site?

Is this a typical 'CDN' policy ? Is this to encourage customers to host only such content that is going to be around for quite a while, and going to see probably a million downloads I started looking at AWS Cloudfront for it's ability stream RTMP media (aka Flash server like behaviour) to host video content. That is to say, I am not too concerned about the "distribution close to client" benefit. However, what surprised me is a clause on the AWS Cloudfront pricing page, that says something like the first 1000 'cancellations' (per month) are free. I interpret 'Cancellation' to the be the act of removal of content that I no longer wish to serve via the CDN. Is that right ?
My requirement is the ability to serve media content (streaming audio, streaming video) which isn't shared with general public or a large audience. It is something like each of these files have a lifetime (or relevance) for only few days (a week or so, at most), and each file will be viewed only by a small handful of people/consumers (e.g. 1 file viewed by an average of 3 people, maximum say 10 people). Also the content's privacy needs to be maintained, so an accidentally shared media URL shouldn't allow an unauthorized person to access it. In this case, is it right to assume that CDN is an overkill, not the right solution ?
I was drawn to AWS CF for it low price (at least, low entry price) for RTMP streaming abilities. What other options could I consider. For me, high availability and round-trip-time are secondary... primary concern being cost, i.e. it needs to be as low as possible. On the question of "how low", I'd say low-enough for developing economies, s.a. in Asia, South America and Africa.

Flash Player 10 specifies:
"Redirects to policy files outside the originally requested domain will continue to cause policy files to be ignored by Flash Player."
Is there a way to access policy files outside the domain?

If you compile a Flash project into a .swf file and that project refers to another .swf file, is it linked statically or dynamically? That is, is the second .swf file contained physically in the first .swf file or does the first .swf file refer to the second at run-time?

I've recently started putting together a Facebook Connect AS3 app and retrieving objects and images through the Graph API.Running anywhere but locally, I receive security errors of the form: SecurityError: Error #2122: Security sandbox violation: Loader.content: xxxx cannot access url...A policy file is required, but the checkPolicyFile flag was not set when this media was loaded.If I add a line of the form:[code]One thing I'd considered was retrieving the crossdomain policy file on a per image basis, capturing the domain from the image URL before making the image request. Unfortunately, at least via the Graph solution (and I haven't looked too closely at the others), their servers resolve the image url after the request is made, from something more generic like: url...Has anyone found a more dependable means of ensuring that images can be retrieved without security sandbox violations? Or do Facebook maintain a definitive list that developers need to keep an eye on?

Anybody got experience with new restrictions in flash player 9 & 10?[URL]..._security.html I have two servers X & Y Y hosts a Y.swf file that is trying to load variable from server X Y.swf has this line of code in it: System.security.allowDomain("*"); now, server X has crossdomain.org file in its root that looks like this:
<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="www.Y.com" />
</cross-domain-policy>
So with this setup everything should work correctly, or so I thought... From what I see variables from server X never make it to Y.swf What do you think could be the problem? Unfortunaltelly guy who has access to the serwer X is not at work today so I can't experiment with adding this line of code just yet to the xml file: <allow-access-from domain="Y.com" /> maybe that would solve the problem..

I'm currently writing a feature for an interactive periodic table which dynamically displays the name of the element and other properties when you hover over the element. I have thought of three ways to do this and I am wondering which is the best, memory-wise and speed-wise, for loading this information.
make a class with an array ( new Array("hydrogen", "helium", "lithium",...etc.)), instantiating it, then accessing the info with object.arr[i] make a class with a static array (otherwise, same as no.1), importing it, then accessing the info with class.arr[i] put the information into an external xml file and accessing it from there. The 3rd method seems excessive as you have to go through the hassle of adding event listeners for URLloader every time. Is there any difference between the 1st and 2nd way? (What is happening in terms of memory when you are importing a class - is the entire array added to memory?)

I have the following:
PLAYER.SWF -- contains flv player and controls.
cross-domain-policy.xml -- that allows everything.
www.yoursite.com[code].....
If I have all the files on the same domain, everything works. The swf is designed to look for the prefs.xml file at whatever location where the html page is. I can have the swf in a location like[url]... and have everything else in some other funky location on that domain. If I try to have the html page and prefs and stuff on another domain, it can't read from the prefs.xml, and I get the Error #2048. From my research, this is a cross-domain issue, but I have cross-domain policies all over the place and it's still doing it.

I am doing a video library. Each category has it's own XML files that feeds it data. Everything works great.However, when I Exported the Release Build. I noticed those XML files are gone(i.e. never got exported). I don't understand why. I need the video library to be dynamic so I can add or remove videos.Anyone know why those files are not exported along with the rest of the project. Like a setting in the preference that I need to fix?

Here's my problem...I cannot figure out how to get the background layer to remain visible throughout the movie once I create tweens for the other layers, without manually copying and pasting frame 1 to every other frame...yikes! There must be something very obvious I am not doing, yes? It probably goes without saying that I am a first time 'designer'.

I have a (self-created) swf demo with button triggering getUrl('SampleTargetPage.html')Now I want to place the swf at our cdn at [URL] while my html page resided on [URL]More structured:
[URL]
I thought it would be sufficient to provide a crossdomain.xml at cdn.example.com to allow the links work. But: it seems like the Flash plugin never queries the crossdomain.xml at all!Now, is there something which I must add in the SWF itself to make this work?
edit: do I need to use Security.loadPolicyFile?
edit: Maybe I don't need the crossdomain.xml at all because everything's under [URL]?

I have a web service running in http://server/abc/service which is being accessed by Flash from a different domain. I deployed a cross domain policy file to http://server/abc/crossdomain.xml and made the Flash load it using: flash.system.Security.loadPolicyFile("http://server/abc/crossdomain.xml");
in the constructor of the main movie clip. However, when the Flash starts, it requests and loads this file (observed in Firebug), but then it also requests it from the root of the server (i.e. from http://server/crossdomain.xml) which does not exist. Subsequent HTTP requests don't work reporting security cross domain errors. When I put the policy file to the root of the server, it all works. Why does it request the policy file from the root as well even thought it loads it from the subdirectory? Why the subdirectory policy file is not enough?
I should also note that the two policy files are loaded before any application HTTP requests are issued.

I have updated the crossdomain.xml security settings for my site - but it seems that the older version is being cached in both IE and Chrome.I've checked the headers sent by the server and it's not sending any cache control headers that would be forcing the browsers to be caching crossdomain.xml.
In an attempt to get around the issue I've also linked to my crossdomain.xml file in an iframe on the site. This hasn't worked though and flash still seems to be using the old security settings.

How can I disable crossdomain.xml check when the executing swf has been loaded on localhost?
Error #2044: Unhandled SecurityErrorEvent:. text=Error #2048: Security sandbox violation: http://localhost:2541/xxx.swf cannot load data from http://www.com/xxx.swf.
I want to assign full trust to the HTML5 web application running locally. I want to disable any crossdomain checks.
Some external servers do not provide crossdomain.xml for their hosted SWF files.
I am running locally. I want to have full trust for debugging purposes.
How do I do that?
I will not consider AIR as it cannot be used from HTML5 application.
Adding the url "http://localhost:2541/xxx.swf" to "C:UsersArvoAppDataRoamingMacromediaFlash Player#SecurityFlashPlayerTrustu.cfg" did not help.

The player loads a flv video file seeon.flv from another domain.Currently, even without a crossdomain.xml in the server where seeon.flv is located, the video is loaded fine.This is not the behavior I want or expect it to be.I also tried putting a crossdomain.xml with the following content:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="none"/>
</cross-domain-policy>
From firebug, I could see that there's a request to the crossdomain.xml before accessing the video file (seeon.flv).It returns the content fine , with the Content-type of application/xml, but it still allow the cross domain behavior.

I am developping this video player: In the exemple above, the player is loading this start image, to display it before the playing of the video:Here, I then tell the player to load the same image, but on another domain: As you can see, it doesn't work anymore. I searched on Google and discovered that I theorically had to add a crossdomain.xml, to make sure that there isn't security protection that avoid swf to load images from other domain. so put these two files on my different domains, to tell the swf to accept files from all * domains

I'm building a Flash based RSS reader, to be run on a kisok, but it's getting tripped up by crossdomain issues. In the abstract: SWF loads local TXT file containing paths of remote RSS feeds (XML files), then loads the feeds stored at those remote paths.
[Code]...
I was under the impression that an single asterisk/wildcard in quotes would mean any domain could access content on that server. But it's not working that way. I've tried changing the Publish Settings to "Access Local Files Only," and "Access Network Only," to no avail. I've also tried adding all of the relevant files to the trust list in Macromedia's Global Security Settings page.

If you want to use content on another server, that server needs to host a crossdomain.xml file allowing access. If this file isn't there, flash won't let you access it. Given that it's easy enough to just write a proxy (say a php script that curls the external URLs) what is the purpose of this restriction? It seems that the content is still 100% available to external people, but there is just one extra hoop to jump through.
