include tag problem

[hesham katon]

Hello Everyone,
I have a problem with include tag .
It works proberly at my local tomcat server , but it doesnt work at my host when I use a relative path with high level directory .
this code works fine :
<jsp:include page="right.jsp" flush="true" />
but this one doesnt work :
<jsp:include page="../false.jsp" flush="true" />
I also tried a code like this but it failed too :
<jsp:include page="/false.jsp" flush="true" />
As I said all of those works at my local tomcat server , so I think the problem may concern with the configuration of the tomcat server of my host .
In fact he cant find the problem .
Any one can help
