Flex :: Can Do Conditional GET Requests From Flash / AS?
Feb 19, 2010
I have a Flex client that loads data from a server to display a chart. This data may change, so the client regularly repeats the request. Since the result may require some work to retrieve, I'm going to have the server detect if the result has changed, and issue a 304 status if it hasn't.I haven't seen any headers in the Flash Player's requests which would indicate that it's already handling conditional GETs. Also, the HTTPService API doesn't seem to provide anything, either. Does that mean, Flash can't do this, or how can I implement this myself?
With regards to cookies, which aren't supported in Flash, I have heard the suggestion to build my own HTTP client on top of the Socket class. This might solve this issue, too, but frankly, I'm really not keen on doing that.As an alternative, I could just cache the result page and send it again, but so far, the API tries to utilize semantics that are already built into HTTP, and I'd like to keep it that way.

Here is an issue i'm struggling to solve for quit some time now.I have a python + GAE backend with a flex client that communicates via JSON. I'm using flex's HttpService bound to a Responder with result and fault callbacks. When python raises an exception, I don't seem to get it in flex. I did some research and found out that the problem probably lies in the fact that the flash runtime cannot handle http responses with status code other than 200.

I am developing an AIR application with Flex Builder that requires me to make two HTTPService requests at the same time. They both use different instances of the HTTPService AS3 class. Both services are calling a RESTful API which is currently running on my localhost (XAMPP) and takes a few seconds to respond (much quicker on live server). The problem is that most of the time one of the calls fails, however occasionally they do both work. Its also random as to which call will fail. Both calls use code something like this. This code is basically repeated in two classes.

I have a couple of remote object methods that I want to respond to in different ways depending on the context, but I'd rather not set up a bunch of different RemoteObject aliases.Some background: Let's say I have an admin application that displays sales stats in different ways. The remote method looks like:
<mx:RemoteObject id="rpt" destination="AMFServer">
<mx:method name="getSalesStats" fault="getSalesStatsFault(event)"
result = "getSalesStatsSuccess(event)" />[code]........
The getSalesStats method takes an employee ID and a sales type as its arguments. You'd call it like:
rpt.getSalesStats(120, "peanuts");
public function getSalesStatsSuccess(e:ResultEvent):void {
salesdata:ArrayCollection = e.result.rows as ArrayCollection;[code]......
I'd like to pass something through the remote method to the responding function, like:
rpt.getSalesStats(120, "peanuts", "clicked button one");
but that of course throws an error because the server doesn't want that last argument.

I'm using Mate's RemoteObjectInvoker to call methods in my FluorineFX based API. However, all requests seem to be sent to the server sequentiality. That is, if I dispatch a group of messages at the same time, the 2nd one isn't sent until the first returns. Is there anyway to change this behavior?

I am using Flex and Actionscript 3, along with Webservices, rpc and a callResponder. I want to be able to, for example, say:
loadData1(); // Loads webservice data 1
loadData2(); // Loads webservice data 2
loadData3(); // Loads webservice data 3
However, Actionscript 3 works with async events, so for every call you need to wait for the ResultEvent to trigger when it is done. So, I might want to do the next request every time an event is done. However, I am afraid that threading issues might arise, and some events might not happen at all. I don't think I'm doing a good job of explaining, so I will try to show some code:
private var service:Service1;
var cp:CallResponder = new CallResponder();
public function Webservice()[code]....
I could ofcourse save the actions in an arraylist, but whose to say that the addToArrayList and the check if other calls are available do not mess eachother up, or just miss each other, thereby halting execution? Is there something like a volatile Arraylist?

I think I inherited bad code, here's the deal: In my command, I create a local var for the remote object and then call a method on it. In the result, if there's no data, I start a timer. This timer broadcasts an event every 2 seconds that continually calls this command until data is returned. Then the timer is stopped.
What we're seeing is that the method returns data once, and then the next time it doesn't (dupe Flex sessions error). It basically alternates. If we click really fast, sometimes we'll get two to work in a row. At times, the Java dev is seeing these requests returned with different JSESSIONIDs. I believe this is causing the duplicate Flex sessions error. I'm using Cairngorm; here's the execute command.
public function execute(event:CairngormEvent):void
{
ruleName = (event as FetchReportEvent).ruleName;
var ro:RemoteObject = ServiceLocator.getInstance().getRemoteObject("quantRemoteObject");
if (model.guid != null)

Currently in my flex application, I've got all of the app's assets being served from my local server, but I want to be able to serve all of the assets from a CDN (URL...)
the application has quite a bit of components so rather than going to each component and changing the source of the asset, is there a way to capture all of the outgoing request from my flex application and run some logic where I can change the request from [URL]...

In AS3 you can pass a constant to the compiler -define+=CONFIG::DEBUG,true And use it for conditional compilation like so:
CONFIG::DEBUG {trace("This only gets compiled when debug is true.");}
I'm looking for something like #ifndef so I can negate the value of debug and use it to conditionally add release code. The only solution I've found so far was in the conditional compilation documentation at adobe and since my debug and release configurations are mutually exclusive I don't like the idea of having both DEBUG and RELEASE constants.
Also, this format works, but I'm assuming that it's running the check at runtime which is not what I want:
if (CONFIG::DEBUG) {
//debug stuff
}
else {

first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.

At the same time I want to avoid sending all three sets and bloating up download size three times.

I have an xml file that has a start date and length of a project... I use a repeater to load each project. The users' screen only shows 2 weeks at a time. I would like to make it so that if a project doesn't fall within the two weeks on screen, that the project isn't loaded. I could do this by sorting through the XML and finding the correct projects to load, and putting them into an array collection, but there's a "move date" button which allows the user to change the two weeks that are showed. Once the two weeks are changed, I would need the projects that fit into that new 2 week window to show.

I have a big loop in actionscript that sends lots of data to an url:
for(var i=0;i<1000;i++) {
var request:URLRequest = new URLRequest();
request.url = url;
request.method = URLRequestMethod.POST;
request.data = data;
var loader:URLLoader = new URLLoader();
loader.load(request);
}
The problem is because URLLoader can make only asynchronous calls, it sends all those thousands requests at once which kills webserver. Also it acts a bit strange on top of that. Lets say the loop is running for 5 minutes. For whole 5 minutes there is no requests coming to web server, then at the end they all are sent at once. I already tried everything I could possibly think of (empty loops, callbacks, delays) - nothing works. All requests are sent at once no matter what. How to make requests synchronous, so it will send one request after another?

In Flex it is now possible to use the -define compiler option to do all sorts of cool stuff.In my program, I am using the option such that some of my code is excluded by blocks like this:
CONFIG::FACEBOOK{
//Some code
}
And this is working well.How do I get a similar behaviour with MXML?I want to do the same thing, but omitting/including MXML tags in this way, not blocks of AS code.

The main top section of the site is a little Flash thing that has buttons as links to different areas of the site. All of that is well and good, but whenever I click those links, it has to reload the entire page (including the Flash app) when only the bottom part changes. This isn't really a huge issue, since everything's real small, but it's kind of annoying.I vaguely remember "fixing" this behavior using AJAX during my web programming class, but that was just straight HTML and Javascript, no Flash players to muck around with.My question is, how do I overcome having to reload the entire page when someone clicks a link from the Flash object? Is there some nice way I can call something other than getURL() to achieve this effect?

As you might know, browser's security model does not allow a script loaded in a page from http:[url]... to make cross-domain requests (no AJAX calls to any other domain other than url...).The Javascript file itself could have been served from a different domain altogether (url....) and that is irrelevant. This is the Same-Origin Policy.
Flash also has something similar? But does Flash treat the origin to be the HTML page where the .swf file was loaded or origin is the domain which served the .swf file?
So http:[url]... loads a .swf file from http:[url].... Now .swf can load resources only from [url].... or only [url....? I'm assuming there are no cross-domain.xml files setup on either [url]....

First off, I'm trying to fix something that I didn't build to begin with and the guy who's project it was assures me it was working fine when he left, although a version I haven't touched since he left seems to have the same issues. I'm also a bit new to programming in general so let me know if I've left out important information in my first post and I will try to add more info.
I have a flash application hosted on-line that acts as a client for a server application written in Delphi. Most of the communication is done using sockets, which work fine. Uploading data files and downloading results files is done using HTTP requests, which work fine as long as the user is making use of an instance of the server on another computer. However, if the user has the server application installed on their own computer and attempts to use it specifying localhost as the url, the socket communication still works, but the HTTP requests don't.
All the socket based communication works fine and, when it is not on the localhost, all the HTTP requests work fine as well, which is why this is so mystifying to me. I've tried changing the flash cross-domain policy file that the server dispatches to be completely permissive, all ports, all domains, all http-request-headers, and still no luck. The Flash app will sit waiting for localhost indefinitely most of the time until I close the server application, and then give this error message:

I am finding that if I load Flash from a HTTPS page [URL] and try to make a request within ActionScript 3 to [URL] the request does not go through. Same goes for the opposite (accessing https from a http-loaded flash script).
The request is failing, the requested data (passed from a PHP script) is not loading.
Now at first I assumed the trouble was with cross-domain policy files, but I have fixed that issue (I think).
Is there any security policy in Flash (CS5 btw) on HTTP vs HTTPS requests based on where the script is loaded from?

I have a Flash based game for the browser which sends users' scores to a php backend script which stores the score and the user id in the database.
Now I have a url like www.example.com/update.php?score=200&uid=234
The problem is that this is very much exposed to an intelligent user, and he can use this url to store whatever score he wants in the DB. Also there's no real user authentication, and I don't intend to have one either, because it's really a tiny game.
How can I stop someone from calling the above url and updating his score on his own.
