Hi Dario, thanks for you reply,
the message is a simple string, at any time (that is not relevant) my LS server send a string to the subscriptor.
on the browser, my app (javascript code) catch the message (the string) and compares it with another string, if the comparison is true my app tells the browser to reload ( window.location.reload(true); )
heretofore work as want to work
the problem is that when the browser reconnects to my LS server (after reload), the LS server send the message again, and my app compares the string again and tells the browser to reload.
this is done indefinitely :S

why the LS server again sent the last message to the subscriptor, when the subscriptor reload the browser??
is this a normal behavior?
how can i fix this problem??

thanks for your help
