Flash :: Uploading Images With Uploadify Run Into IO Error With Local Proxy (proxy.pac)?
Feb 21, 2010
I'm trying to upload images with Uploadify but I run into IO error. I have gotdemo and it works on my computer, so I decided to implement functionality of my application to this example step by step to catch the error and discovered that the reason of IO error is my local proxy.pac (I use FF):
function FindProxyForURL(url, host) {
if (shExpMatch(host, "*.app.local*")) {
return "PROXY 127.0.0.1:3000";
We have deployed a flex application on Tomcat and it uses Blaze-DS to communicate with the Java side. However when using the deployed application we constantly get the error: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. url...Within our Apache httpd.conf we have set up a proxy lookup so that rather than using particular ports (e.g 8082) we want to use port 80 (some of our customers operate in a locked-down environment).[code]
How do I get the clientIP from users in my regisrtationforms? It's easy to get the IP with the user isn't using a Proxy, Proxycacade or VPN. But if he uses one of those its difficult. X-Fowarded-For isn't reliable and fails within cascads.
But there are possibilities, because JavaApplets and Flash aren't using the Proxy-Services. How can I archieve to get the clientIP with those technics? I prever to use a small Flash-Code to get the IP from the client, but how to implement?Another way should be a counterpixel which is using IPv6. Most of the proxyservices only support IPv4, can I tell an image only to use IPv6?
I'm trying to use JMeter to test our web application and I'd like to use an automated recording of tests but our UI is in flash/flex. Is there any way to get the proxy server to cooperate with the flash/flex? I do have control of both the client and server sides, though rewriting our application to redirect the flash/flex calls to another address isn't really an option. If there were an automated way...
I'm currently testing Windows client and server, but I also need to support testing on Linux client and server. If tests need to be created on one or the other and can be ported to both I could live with that.
I am working behind a proxy and some of the flash uploaders out there require me to authenticate myself on the local proxy before allowing me to upload files. I have such an uploader which currently is outside my network. However after it tryes to execute file.upload(request); it dies silently without a trace of what is going on. I presume that it fails because it hasn't requested the proxy auth. How can I show the proxy auth login pop-up. Here's a sample of my code
ActionScript Code: var request:URLRequest = new URLRequest(this.uploadScript); request.method = URLRequestMethod.POST; request.data = new URLVariables();
I asked Google. But there is no working answer for it. I checked "right click -> global setings" and found no proxy setting in [URL].. Can anyone know how to configure proxy settings for flash player?
I'm trying to get a JSON response from an API into Flash using a PHP proxy (and decoding in as3 using as3corelib), and I can't figure out how to test this.
If I run an html/js file that is using the proxy to get the same data, it works, so I know that there aren't errors in my php file.
If I use my as3 to directly call and parse data from a different API (not using a proxy), I can get the data ok.
But if I run my swf trying to connect to the proxy file and get results, nothing happens. I'm not really sure how to trace what's going wrong. I assume I have to test the swf on the server? Or does just the php file need to be on the server and I can test the swf locally (this would be WAY easier)?
Here's my code:
Code: package com { import flash.events.*; import flash.events.EventDispatcher; import flash.display.Sprite;
Lets say I have a PHP application using very cheap shared hosting. What is the best way to stream audio/video (mp3/mpeg) that is tens of megabytes to hundreds of megabytes in size. I am thinking of a PHP based cross-domain proxy that uses caching. Is there something wrong with this approach?
I am creating a google scraper in Adobe AIR using the Flex 4 framework. I have run into a brick wall: Google forces a captcha after around 10 pages are read. Can anyone tell me how to get the page through a proxy server
I'm trying to use uploadify to upload images to a remote server. I've have done everything I can think of for the cross scripting issue or whatever. Here is what i've done. scriptAccess to 'Always' in the uploadify function. I have a crossdomain.xml on my ww2 server with uploadify.swf in the root as well. I have uploaded my javascript jquery lib file to the remote ww2 server and put it in the header I put the jquery.uploadify.js and the swfobject.js in the root directory as well.
If I try to click the X to cancel a file I get the error: Error calling method on NPObject Or uploads don't work either. If anyone can help with this that would be great. If there are any other good flash based or non flash based multi uploaders that will do remote files with no issue please let me know.
How can I post a tweet directly to twitter without needing to use a server-side proxy script (ie, tweetr)? Can a twitter API call be made directly from a swf?
I am trying to develop a P2P conferencing application in flex using RTMFP. So I have to make connection to Adobe Stratus server for Id of Flash Player instance. I am a student and behind the http proxy. I have checked in NetConnection class but, didn't find anything related proxy configuration.So, How can I configure proxy settings for my flex application.
So I need to retrieve XML from a public API, but my app is in Flash and the public service won't implement a crossdomain.xml file. I found this PHP script online (below) for a proxy to request the URL. It works fine for URLs like:
[URL]
but the script seems to either strip or ignore any arguments on the URL, like:
[URL]
I'm PHP ignorant. Is there an easy way to have this script process those URL arguments? Here is the script:
Is it possible to use Apache to proxy/tunnel RTMP(S) traffic through to Flash Media Server?Basically, I want to tunnel RTMP traffic using HTTP through Apache.What I want to be able to do is open up an appropriate port (either 80 or 443) on the Apache server and have that proxy traffic through to Flash Media Server. The reason I ask is that I have set-up this scenario but I keep getting a "NetConnection.Connect.Failed" error message; I captured the network traffic flowing between my machine and the server and it is connecting to the server, just nothing happens after that.Do I have to connect directly to Flash Media Server?
I know I can call my server directly from javascript. However, I want to do this through a non-GUI SWF file. I'm fairly new to Flash but have gotten all the CS3 tools from work. Does anyone know of any examples on:
1. how to make a web request from within flash provided the URL, post content, and timeout
2. how to call a Flash API from javascript asynchronously
3. how to detect whether the browser being used can support my SWF (I don't want it to prompt to install Flash if they don't have it yet)
I'm actually hoping someone has already done this and has a sample already built.
I want to use a proxy on the HTML Control found in Adobe AIR.I have tried looking at the AS3 docs on Adobe but honestly, it didn't explain the usage clearly to me and looking at Adobe's example, I can't seem to make out anything off of it.
I'm using a PHP proxy script to load images from Facebook into Flash without any sandbox violations. It is taken from the guide here: [URL].. The relevant PHP code is:
[Code]...
The guide mentions that additional security measures are recommended for a real world application. What additional measures would be applicable to this? Maybe some kind of key passed from Flash to PHP?
I realise that there's nothing I can do to completely protect the Flash from being decompiled, but can I prevent the script from being used maliciously?
I've run into a peculiar problem while trying to make use of the Proxy class and override the getProperty() method. I've attached my example class code below:
I have an AIR app that I need to define a proxy for because the services sit behind a firewall. We are not using BlazeDS so I can't define the proxy settings in the proxy-config.xml file. So, how do I do it? I'm guessing that I'm not the first person who has had to work behind a firewall when accessing data so I'm not sure why I can't find any documentation on the web anywhere about this.AIR says it is supposed to automatically know and use the proxy configuration from your system, i.e. default browser. In there, I don't set a manual proxy, I use the 'automatic configuration' and point it to a .dat file. Could this be where the problem is? Does AIR not know how to understand this?There's no way to set a proxy on an HTTPService component unless you are using Blaze DS or LCDS? Is this true? I'd hate to have to add that to my application just so I can get this accomplished.
I'm trying to implement a dragging system which can only be described as similar to dragging the map on Google Maps. I can set up dragging easily in Flex, but unfortunately the standard model of dragging i.e. dragging an element proxy and dropping it in another element is not what I'm after.
Is there anything built into flex where the actual element rather than a proxy can be repositioned in a different place within the same parent? Or will I have to hand code something using mouse events as you would if implementing a solution in JavaScript?
I have a problem using Flex with BlazeDS on a Tomcat 5.5 through a Proxy (Apache). I already searched for it but didn't find answers which solved my problem. I hope you guys can help me out. Our scenario is the following: Flex-App using BlazeDS to communicate with our Dataservice on a Tomcat 5.5.The Webapp is balze enabled and the services config contains channel definitions like the following:
So I have a PHP proxy that gets information from a website. Let's say the proxy gets the information from (www.example.com). It checks if the number of lines returned is the same as before, if not then there are more lines, it counts the difference then it need to push this information to the Flex client saying that it has new information, (x) more lines have been written.I am not really sure how to do the push mechanism on the php proxy because I am not sure how to actually push from the proxy to the client, never done it before.
After reading James Ward's post I'm considering using a proxy rather than a crossdomain.xml file. I have a java app, which includes a flex applet, on one tomcat instance and a java web service on another tomcat instance. Does it make sense to have a single (Apache httpd) proxy handle requests for both the app and the web service, thus eliminating the cross domain restriction?how to deal with the cross domain issue are welcome.
I am having some issues trying to make an AIR application connect to a RemoteObject when the application is run in a domain that has proxy servers for outbound connection.The error provided is as below:
