Re: [Flashcoders] Forcing XML connection closed from SWF
Here's some random ideas: - The keep-alive option is a good thing (everything goes faster) and normally does not impose a problem. If you have a problem on the "server" because of that (too many threads or too many sockets taken), always remember that it is the responsibility of the server to control this and not the client (browser). - Note that the connection should disconnect by itself after some time. Did you measure how much time you had to wait? (probably a couple of minutes). I think it should never be "foreever". Maybe you did not realize this timeout potentially makes this less of a problem. (?) For Internet Explorer, the keepalivetimeout registry setting is "KeepAliveTimeout" under: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings - If you just want to turn off keep-alive temporarily just to do a test on your machine, it is possible that you can turn it off in your browser's options (set it to not use HTTP 1.1) or by modifying a registry key. Or else, you can try to find a proxy or tcptunnel that could force it "off". - A potential "brute-force" solution (not sure it is really reliable): I know that you can control the keep-alive on a request-basis by modifying the http headers (at least in IE). You can try to use XMLHttpRequest (from javascript) and force to turn off the keep-alive option by setting HTTP Headers. That is - after you finished doing your XML query. -- that's on the client (browser) side - Make many connections to be sure you saturate all the available connections (something like 2, 3 or 4). - Make sure you use a "keep-alive-friendly" proxy (or tcp tunnel) to really "test" that the connections are kept alive and that your method really makes a difference. - I do not know if we can control the HTTP Headers from within flash - if you can, try to "modify the headers" to shutoff the keep-alive option. It *might* be possible with the recent flash player 8 (raw sockets). hope this helps, B. 2006/4/21, Nathanial Thelen <[EMAIL PROTECTED]>: > > Thank you for the idea on that one.

Thank you for the idea on that one. I am particularly looking for a browser side only solution in this case.

[Flashcoders] Forcing XML connection closed from SWF
I was wondering if anyone out there know how to force a XML connection closed once the onLoad has happened? The way it works currently is that if the webserver has keep-alives on, the connection to the server stays open. I am pretty sure that the browser controls this, but would love to hear any ideas on the topic.
