  Socket Server

  Mar 22, 2009 02:13 PM | LINK

  We are just testing Beta.3 and socket server functionality and cross domain files. but have some problems.
  We have made a financial application in Adobe Flex, and we are thinking of porting this to Silverlight, now that it is becomming mature and with a set of controls.

  A problem though, our Streamserver runs on port 80, which the silverlight app. must connect to (since many banks does not have other ports than this open)
  The Streamserver also sends out a cross-domain file.:

  <?xml version="1.0" encoding ="utf-8"?>
  <access-policy>
    <cross-domain-access>
      <policy>
        <allow-from>
            <domain uri="*"/>
        </allow-from>
        <grant-to>
          <socket-resource port="80" protocol="tcp" />
        </grant-to>
      </policy>
  
    </cross-domain-access></access-policy>

   This doesn´t work. Any ideas? The documentation on the .NET is very confusion and of various quality

  Thanks in advance

  For those interested This is the application in question:

  The first think that happens when you connect, is that the streamserver sends out a cross-domain file giving access to port 80. But not in SIlverlight so far. :-(

  Silverlight applications can only connect to sockets in the range 4502-4532.  You cannot use port 80 for your application.  There's a somewhat heated conversation on this topic here:  http://silverlight.net/forums/p/81467/192712.aspx

  Shit [:(]

  No reason for us to even consider porting to Silverlight parallelly with our Flex application. It would be a completely no-go not to use port 80 to access the stream. Much people would use our application during work hours, beeing at work, and other ports that web, FTP, STMP will be closed.
  Too-bad, we could have used the multi-thread capability of Silverlight which is not present in Flex.

  If you need to use sockets ther is nothing to do.

  But if you can change your transport you may consider the usage of a webservice.

  But if you are talking about streams probably this is not your case.

  What are you streaming?

  Hi,

  I've posted an updated example of Duplex support in SL3 here: http://www.davidezordan.net/blog/?p=935

  Hope this helps.

  Hi

  Thanks for your suggestions. [:)]

  But it is simply not an option for us to start modifying our serverbase, this is standard socket servers, that has 3 different clients connected. We want to use standards that are not bound to OS´ses. So doing a WCF service, that is not released yet is not a viable option

  We just hope that Msft realized that is is not neessary to make stricter restrictions that the one Adobe has imposed throught their Domain policies.

  Hi Lars, The lack of arbitrary socket ports is indeed silly. But even with Flash or even if SilverLight did support sockets over 80, you still need to support connections over HTTP. Some corporations behind proxies simply do not permit socket connections and you must go thru the proxy.

  Here's a note for you: Flash in Internet Explorer has a problem with version detection. This is noted as Flash suddenly stops working in IE. It's not flash that has stopped working, it is the version detection that has stopped working.... Your site failed in IE because of it... saying you must install flash etc...

  The version detection occurs in AC_RunActiveContent.js. You can read about my solution for the problem here:

  http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=72&catid=675&threadid=1436087&enterthread=y

  Here is my own version of socket and HTTP connection support in the form of a Real Time Blog:
