[flexcoders] Re: Cache-Control header not working in HTTPService
The http headers to control (and avoid the cache) come from the
server side, that is, it is not useful at all that you set the
headers from the client side.
In order to avoid cache you need to set the header Pragma with the
value no-cache and also set Expires with -1 to give your
content an inmediate expiration, but remember: set these values from
the server, not from the client.

the way it is supposed to work. The server indicates that the
content
it is returning is dynamic in nature and should not be cached.
While
adding the current time to each of your requests as a parameter
will
avoid caching, it is a bit burdensome if you have a large system to
implement. Note also that the no-cache response header is ignored
by
IE/flashplayer when your request is over https as described here
http://blog.fastlanesw.com/?p=9. Note: I also describe the
workaround
that I use to get around this issue.

Hi y'all,
I've been having this problem for a while now, and I've went
by
the docs on RPC components time and time again, getting no
solution for this.
I have an HTTP service and I need to guarantee that its
results
are not cached by either the app or the browser.
My last attempt on this is:
mx:HTTPService id=myService
concurrency=last
headers={new URLRequestHeader(Cache-Control ,
no-cache)}
makeObjectsBindable=true
requestTimeout=10
showBusyCursor=true
useProxy=false
url={myServiceURL}/
When debugging the app, the service's HTTP header property is
populated by the URLRequestHeader, so I believe It's getting
built
adequately. Also, when inspecting the AsyncToken returned by
myService.send(), the message property has its headers also
populated by the URLRequestHeader.
The thing is that when I check for adequate reception on the
server side, I don't get the Cache-Control header at all.
Does anyone know how to make HTTP headers work for
HTTPServices?
TIA,
Guido.

[flexcoders] ByteArray.readMultiByte bug on Macintosh?
Hi,
I have isolated a problem that appears only when a SWF (built using
Flex 2.0.1) runs under Macintosh:
The flex application reads a binary data package (serialized on a
windows server) using an URLLoader
In that binary stream the server serialize things like numbers,
single bytes and strings.
All is OK with the de-serialization of the data except with strings.
They are serialized in a very simple way: first a byte containing the
string's length and, then, the characters stream encoded
using Windows-1252.
When the application tries to de-serialize such a string, it first
read the string's length (ByteArray.readByte) and then, it tries to
read the string body using ByteArray.readMultiByte() method.
The result: when the client is a windows box (using firefox or MSIE)
there is not any problem. However, when the client is a Mac box (OSX
10.4 with FireFox) readMultiByte gives a different result each time
it de-serialize the (same) binary stream.
The function where the problem is isolated is the following:
public function readString(binData:ByteArray):String
{
var str:String=;
var length:int = binData.readUnsignedByte();
str = binData.readMultiByte(length, Windows-1252);
return str;
}
I think that I could get rid of the problem by reading each single
string's character and applying my self the conversion from Windows-
1252 to UTF-8, but I would like to rely on ByteArray.readMultiByte.
Have anybody out there found also this problem?
Perhaps it is not a problem and I am doing something in the wrong
way, Could anybody help?
Thanks in advance.
[flexcoders] Re: Convert ByteArray to Bitmap
I agree with Franto friend: You need to know something about the bytearray you are receiving, i.e. format, disposition, etc. Most of image formats have a kind of header where you could find its width, height and so on. Once you know the dimensions and the format, you would need to use the apropriate decoder to transform the bytearray in pixels of a Flex Bitmapdata object. --- In flexcoders@yahoogroups.com, franto [EMAIL PROTECTED] wrote: if you dont know what is it ByteArray how you want todisplayit :) you have to know at least 1 parameter, width or height... thats my opinion Franto On 1/26/07, Steve Cox [EMAIL PROTECTED] wrote: All, I'm retrieving an image via remoting as a ByteArray.

[flexcoders] Application's creationPolicy
Hi guys, As far as I understand, the Application is a container and containers have a creationPolicy that affect to the moment where container's chidren are instantiated. Moreover, there are many examples showing how to createChildrenFromDescriptor. The problem comes when one (me) need to defer the creation of application's children until a more apropriate moment: if I set the application's creationPolicy to none, then, initialize nor creationComplete events are never fired (?) The fact is that I would need to be sure that all my external styles (CSS compiled) are properly loaded before any application´s children start to instantiate or initilize. I have succeded by inserting an instrumental container between the application and its chidren but I'am wondering if it is really needed. Any ideas.
