javascript - window.open does not reuse existing named window? -


we have application running in tomcat 7

we trying open window our application using javascript, each time event called using window.open('url', 'name', '');

but happens each time event called new window opened , information loaded, should open 1 window first event , following events should reload information in same window.

we able avoid situation, did was

we used call our application deployed in different server url follows (http://servername.domain.com:8080/applicaationname), above issue happens

but when call http://servername:8080/applicaationname, works fine expected

what causing behavior?

many thanks, cheers.

in internet zone (which code runs when use fully-qualified-domain-name servername.domain.com) code has restricted permissions. in intranet zone (which code runs when use dotless hostname servername) there fewer restrictions on permissions.

the problem you're encountering in internet zone, named window launched site "a" may not navigated javascript site "b"-- instead new window created. introduced change in ie8 security reasons, , matches other browsers , html5 demands.
