streaming channel connection sharing

-

hi,


i have trade application showing different views. every view need real time data push server pushing updates prices , other details. learnt documentation of blazeds straming-amf channel fallback plan polling amf channel way go.

this fallback required max connection per session can reached because of long lived http connection of streaming channel.

however mentioned application setup hit scenario because have 3-4 views need real time push server.


i read articles other ajax based library. http://blog.icefaces.org/blojsom/blog/default/steve%20maryka/

it allows share single long lived http connection across different views, portlets.


so,

i)  possible use similar technique/workaround in flex such can share single connection , still keep using streaming-channel real time push ?

ii) read hack use subdomains overcome browser per session connection limit. how recommended approach ?

iii) , provided there no support/approach in flex such cases - how expensive polling method client ? add overhead client , server ?


any appreciated.


thanks,

mithun
