RE: [flexcoders] Cross Server Socket Connection (NOT XMLSocket)

[Steve Cox]

With XML sockets you could send a policy file over the wire through the socket itself, however as you’re not going to be able to do this with a telnet server I’m not sure you have any options.   Only work around I can think of is to write a bounce app that runs on your webserver and relays messages to/from the telnet server. This could have security issues for you however.   -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ralf Rottmann Sent: 01 December 2005 15:33 To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Cross Server Socket Connection (NOT XMLSocket)   You’re right, Scott. The policy file needs to be on the *destination* server – and that causes the problem. In a socket world the destination server might not even be a web server. E.g. the server could be a simple echo server which just sends back all text received on a specific port. You could e.g. telnet the server:   telnet 10.1.1.10 >helo >echo: helo >i send this command >echo: i send this command >exit >echo: bye   So the server waiting for a socket connection does not even know anything about policy files including not how to server them back to a flash client.   The question remains: Can a flash player open socket connections to *non web servers*. If not, this would mean  a no go for a whole set of RIAs.   Ralf Rottmann From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Steve Cox Sent: Donnerstag, 1.

This was certainly the case for XMLSocket, not sure about binary, but I’ve not heard it’s any different. (Doesn’t mean it’s not different though).   Ie if you are connecting to myserver.com port 7000 you’d need a policy file at http://myserver.com   Again, I’m not 100% sure on binary socket, but xmlsocket certainly acted like this.   http://livedocs.macromedia.com/flash/8/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00001623.html           -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ralf Rottmann Sent: 01 December 2005 15:17 To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Cross Server Socket Connection (NOT XMLSocket)   Any idea how that should work?   You call the Socket.connect(server, port) class to establish a connection (and that connection GETS established even without any policy files). On the “other side” there is a simple echo server. Who and how should the policy file get served via the socket? Where should it be placed on the simple echo server? I doubt that it works with policy files.   Any ideas?   Ralf Rottmann From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Steve Cox Sent: Donnerstag, 1.

E.g.: If I want to create a simple telnet client, host it on my private web page and want that telnet flash movie to connect to whatever server out there. Obviously policy files do not work as socket does not attempt an HTTP connect.   Regards   Ralf Rottmann   -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
