HOW TO HIDE/IGNORE ?RVN in Icefaces

Hello fellow developer,im getting problem when i have to hide the, for example, 开发者_C百科/Login.html?rvn=1, i want to hide rvn parameter in icefaces,s that possible?iam using icefaces 1.8.2..

i have searching that method and o found thats a way to hide rvn,by adding in web.xml,

<context-param>
        <param-name>com.icesoft.faces.ignoreRvn</param-name>
        <param-value>true</param-value>
</context-param> 

but,the rvn is still shows up,could everyone help me?

thanks for your comment n sorry for my bad english :D

I thinks the best way to do this is by using prettyfaces,so we can hide the the url in icefaces,and using custom url,,we can hack it too :D
