Professional :: When Using IE7 For Parallel Https Calls Across Two Servers
Jan 6, 2012
Weeks back I faced a wierd issue in the behaviour of flashplayer running on IE7 which is invoking parallel https calls. I have two SSL enabled servers one is listening on port 443 and the other is listening on port 8443 but both running in the same domain. I developed a flex client (using httpservice class) which sends parallel https requests to these two servers. When the number of parallel requests increases say more than 5 requests to each server, the fault handler was encountered with the error message:[code]After breaking my head for a long days, I got one solution which would work. This issue is happening only if we are sending https requests to different ports in the same domain. So rather than moving one among the two servers to a new domain, I got a new DNS name for the same destination. So presently I got two DNS names pointing to the same machine in which both the servers are mounted.Now that I am using a separate DNS name for the server listening on port 8443 and the old DNS name is used to hit the server listening on 443.

I have the following application in flex. I want to call two different remote objects in parallel.
[Code]...
Now what the methods do is to print sth. when they are called, then wait 8 secs and print sth. after that. When clicking each button seperatly, it works, both methods are started in parallel. However, calling both method the same time, leaves one service to wait with its call while until the other is executing. How can I avoid that?

I'm on Flash Builder 4.5 and I'm using remote object with amfphp and when I call two method (method1 and method2) at the same time the response of method2 always arrives after method1's response even though method2 is much more faster to return the result.re's the scenario:I set a remote object which refers to a remote php class "Newletter" which contains the sendNewsletter and getProgress methods.Here's the code:-sendNewsletter() reads the email archive and send the newsletter. After each email has sent it writes a log into the database.-getProgress() reads the log wrote by sendNewsletter, counts how many email have been sent, compares it with the total number of the email that have to be sent and return the progress percentageFrom the flex interface the users select a Newsletter to be sent and click on a "send" button which calls a function that calls the sendNewsletter() and then instantiate a loop of calls to getProgress (as you can see when getProgress returns something it calls the setProgress which updates a progress bar and calls getProgress again until the progress percentage reach 100%.
So right after I call sendNewsletter() I call getProgress() on the same remoteClass().sendNewsletter() can take several minutes to complete (in my tests for sending 4 email it takes about 4 seconds so I think that sending thousands of email will take much more!!) and the trouble I'm encountering here is that getProgress() result arrives only after sendNewsletter() concludes its execution while what I would like to achieve is:

My webapp with flash files (fusioncharts that reads XML data)works well in Firefox, but not in Internet Explorer. The problem
isn't that I can't get the XML data (the Pragma and Chach-Control header, when you get a "Error in loading data") because I can load a Excel file with html data. I get a Movie not loaded error instead, like if that IE can't load the swf file.I tested the application on another computer with https on IE and that didn't work, but it do work on regular http in IE.

I have a Flash movie that uses Actionscript 2.0 to trigger animations. The swf and flv files are separate though - the flv is called by the swf. There are cues in the flv that fire Actionscript events. How can I get the whole thing to export? I can convert the flv to an avi but I need the animations.

I have a loader class that has a container and loads in swfs using Loader class. Within the loaded swf on the last frame of some nested clip, I have a call to a static function within some "Connector.as" class. Now what happens is when I try to unload the swf ( by removing all listeners, calling loader.stopAndUnload(), and setting all references of loader to null) before the nested clip calls the static funciton, the swf gets unloaded and garbage collected (all enterframe events etc. are removed because they no longer run) however even though there is no reference to the swf the nested clip still plays in the background and dispatches the call to the static function when the frame is reached

I've got a website where I want people to be able to upload their own SWFs which are then displayed on the page - mainly for timed image displays etc...I'm concerned about javascript security as flash can call JS functions, theoretically if you knew which JS commands to call (e.g. some AJAX stuff) then external people could do some real damage.So my question is, is there anyway I can disable calling javascript from within flash? Possibly something in the embed object paramaters tags?

Using the web services panel, I've connected to a web service, but all the method calls will only show the param structures/types - not the result structures/types. To the best of my knowledge, I'm sending the right parameters, in the right structure, but always I get an empty response.The web services panel:
Debugger results (with breakpoint placed just after a response is received):
Where might the problem be?

My problem occurs when I try to load multiple images in one class in AS3.[code]My problem with this is, that every complete-method receives the same image. Sometimes they all get img1.jpg, sometimes they all get img3.jpg....I don't have any clue why this is happening.[code]Now the different Bitmaps and Loaders have distinct names and are called within the same method call. The event handlers now are inline.

I want to dynamically load several png images from 6K to 2,5M. I create the loaders in a for loop and start them all at the same time, and listen Progress, Complete, IOError and SecurityError on each loader. The problem is the COMPLETE events are not always fired, even if Progress events show all images are fully downloaded.
I tested with Firefox and Chrome, I load 4 images 2.5M, 2M, 1M, and 6K, then I just get 2 or 3 COMPLETE events, sometimes the 4 are fired with Chrome. Did not find any workaround. I tried to listen ProgressEvent and call the completeHandler when bytesLoaded == bytesTotal but the loaderInfo.content is null (and bytesAvailable =0) so I can't get the Bitmap.
1) Is there a known limitation in the number of simultaneous loaders, from flash player or browsers ? Does Adobe recommend to have queued loaders instead of simultaneous ?
2) Is there a way to get the loaded Bitmap when COMPLETE is not fired ?
3) I don't keep the loaders in a property of my class, and use weakReference for the listeners : the issue can come from my code ? (but the ProgressEvents are received until the download is complete)

We have a flash website built using flex and CS3. Majority of the site has been done using flex. We have multiple flash movies on a page and we obviously have the page loading very slow. Now that we are looking into options for making the page fast, we are trying to understand whether we can run these flash movies in parallel ? Is there some provision in CS3 to make the flash understand that this object will be loaded and ran first and then the second object.

In one situation we have one movie that chooses randomly to load one of two other movies. On one server it works fine. On another server, flash says there are no errors and that it loads correctly (i tested this using onLoadError and onLoadInit). There are no errors and the onLoadInit is called correctly, but what is in the movie wont display after being loaded.In another situation, the user can upload a photo to the server and then that photo is used in the game. The photo upload works properly, the photo gets put on the server and all that jazz. Now on the one server, the loading of the image works fine, it shows up and everything. But then on this other server, yet again the photo says it loads properly with no errors, but it doesnt dipslay it. But I can go on wiht the rest of the game working fine... just no photo... has anyone run into this before?
Oh yes, and it also works on my home server, so it works on two servers and not this other one. So that makes me think it's a server issue, but if that was the case wouldnt flash throw errors if it couldnt work? And like i said, flash at least says it's loading the photo correctly!

I've created a highscore board which uses Flash (AS3), PHP and MySQL. Works fine when all the files are on the same server.However if the swf is on a differnt server (let's say serverA) and the PHP and MySQL are on serverB then it doesn't work.By the way this was the error message...Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://...etc.

I know that you can grab your web server's current time with php, .net, or whatever server side scripting language you have available, and create a variable to feed into your flash movie at the embed time.What I am wondering is if there is a time server out there with an XML feed that you could connect to with flash to grab the current time based on whatever parameters you feed into the query string.I would doubt such a thing exists (at least for free) since so many people would probably tap into it and overload the server with requests, but it would be an easy way to set up someone's flash movie to grab a somewhat accurate current time stamp at load time (or any other time you'd want to call on it) without the need for server side scripting.

Hudson
TeamCity
Both seem to be popular on the general level but have you got some direct experience with using one or both with Flex development? Or would you recommend some other tool?

The camera control panel goes awayCould it be server configuration? Settings? Security? Why would it be different on different servers, all things being equal?

I basically have a movie clip on one server and swf clips on a different server, and I am loading them using the loadMovie command.my problem is: on those movie clips I am loading, I have a stop(); action on the first frame, and I am triggering them to play when loaded by the containerMovie.play(); commandmy problem is: if both parent movies and loaded movie are on the same server, the action works fine and the movie is played on when the frame with the play action is reached.if they are on different servers, the movie is loaded alright (you can saee the first frame) but the action does not get executed and the loaded movie does not playexamples:[URL]

I'm working on a multiplayer game. basically need chat, rooms, login (user management).where i confused myself is with some different (or maybe the same) remoting technologies.I can do what i need with Flash Media Server, and have already purchased an influxis account. It uses FMS and SharedObjects.
Latency is a big issue for me, is there a difference between Socket Servers, AMF, and FMS ?can FMS be a SocketServer serving bytearrays ?is AMF a wrapper for data being sent to socket servers? if FMS is a socket server, can i use AMF for FMS?and which is the fastest? is SharedObjects on FMS fast enough (instant update) ?

is it possible to connect to two different BlazeDS servers from the same Flex app? I have already read this question: Can a Flex client app connect to BlazeDS running on a different server? However, it appears to be discussing the possibility of connecting a Flex client to a BlazeDS on a different server but not necessarily to another BlazeDS on a different server.
One Flex client connecting to two webapps using BlazeDS - Detected duplicate HTTP-based FlexSessions
In attempts I have tried, I get the error mentioned in the second question above: Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly.
Is connecting one Flex application to two BlazeDS enabled servers completely impossible? We want to be able to have a "common functionality" BlazeDS server that is used by a number of Flex apps that each have their own local BlazeDS server for their own functionality.
The way I'm currently doing it:
In my mxml file, I'm defining a a channset like so:
<mx:ChannelSet id="dataService1Channel">
<mx:channels>
<mx:AMFChannel id="dataService1AmfChannel"
[Code].....
The calls work and I can get the data but I'm getting that warning I mentioned in the form of an alert in the Flex application.

i uploaded the same copy of a website to 2 different hosting for testing. the preloader that displays the percentage loaded when u click on a SECTION in the site (not the very first 1 tat appears before u enter) is done using the movieClip Loader Class, the preloader bar & percent text displays correctly on 1 server but doesn't on the other. My guess is the bytesLoaded n bytesTotal parameters are undefined in the "not working version".[URL]
Code:
var mcLoaderA:MovieClipLoader = new MovieClipLoader();
var listenerA:Object = new Object();
mcLoaderA.addListener(listenerA);

I am trying to load test my 2 server load balanced FMS 2 environment which has been set up with the profile for 1000 connection 40MB. When I hit about 140 connections/server it fails with a "Bandwidth Penalty activated at time 1248945759.731000 with bandwidth 5945889 and limit 5000000" error logged in the event viewer immediately followed by many rejection errors: " immediately followed by many rejection errors: "
Connection rejected by server. Reason : [ License.Limit.Exceeded ] : (_defaultRoot_, _defaultVHost_/DLvideo/_definst_) : Current server bandwidth usage exceeds license limit set. Rejecting connection."The load testing mechanism is a test harness that was created by a third party and seems to work well up until the above messages are logged. It basically is making 25 sustained streamed video connections per minute until it starts disgarding connections as noted above.
The servers are not even breathing hard (RAM is less that 50% consumed and CPU Utilization is < 5%) 1GB NIC on each server.What parameter(s) can be changed to push the servers harder.

I'm planning on building a Flex based multiplayer game, and I'm researching what will be required for the server end. I have PHP experience, so I started looking at ZendAMF.
Now in this game, I'll need the concept of rooms, and real time updates to clients in those rooms, so it looks like I'll be using remote shared objects (correct, yes?). I'm not seeing where ZendAMF can support this.It seems to indicate that ZendAMF isn't going to do what I want. WebORB for PHP seems to be the only PHP based solution that does messaging, but on that page it doesn't mention "real-time" next to it like the Java based ones below it do.

I run a FMS 3.5 Server and I want to add additional FMS Servers and load balance the traffic. The plan is to use a script for the developer version of FMS that forwards two incoming FME streams to the different servers, so each FMS Server has all streams. Is there a script for this? In addition there is a need for a script that somehow redirects the users to the server with the lowest users/bandwidth in use.
