    Question Multiple browser tabs

    Hi everyone

    Is there any known limitation about how many Flex apps using a Lightstreamer connection you can have in a browser?

    In Firefox 6.02, we can have 4 tabs all streaming, but any more than 4 get no LS data.
    In Chrome only 2 or 3 apps get LS data, and throughput degrades as you add apps.
    In Internet Explorer 9.0.8112 usually only one tab get LS data, although sometimes a second can work (but usually not).

    All the apps get data from other servers fine, its just the push data from LS that stops.

    Am I missing something really obvious? Just a bit perplexed as to what the limits are, and want to learn what is influencing this.

    Thanks in advance for any help or pointers anyone can give me on this.

    Hi,

    yes there is a limitation; a limit is posed by browsers on the number of concurrent connections open to a certain server.
    Actually the http protocol dictates a maximum of 2 concurrent persistent connections per client(browser)/server but most browsers permit more connections.
    [You can act on this limit on firefox by changing the network.http.max-persistent-connections-per-server setting in the about:config page]

    You should be able to work-around this limit by using different host names in each flex application instance or by letting only one flex application connect to the server and connecting the others to the first one using Flex's LocalConnection class.
