Hi,

due to the same origin policy both host names must share the same domain

WRONG:
Code:
domain: myportal.co.in
ls server: push.CO-OP.co.in
web server: www.myportal.co.in
CORRECT:
Code:
domain: myportal.co.in
ls server: push.CO-OP.myportal.co.in
web server: www.myportal.co.in
CORRECT:
Code:
domain: myportal.co.in
ls server: push.myportal.co.in
web server: www.myportal.co.in
No response was received from Lightstreamer for both of the above..
There should something else wrong.
Can you actually reach the Lightstreamer server opening directly its url in the browser (remember to put the port in the url if such port is not the port 80)
Did you try to check which connections are made by the browser (you may use firefox+firebug to check this)?
Did you see any javascript error?

i try to browse the url as "http:\\www.myportal.co.in\Access"
where "Access" is the application for which a virtual directory is created in the server system.
We don't get any response when we browse from a remote system without any host entry.
Can u please help us how to resolve this issuse?
are the host names configured in a DNS accessible by the client machines?
(note that urls are written with slashes not with backslashes)
