[ic] How to disable browser's back button

[interchange-users@interchange.redhat.com (murahashi)]

How to disable browser's BACK button on the nextpage(C) from the previous
page(B)?
For example, Page A is form INPUT page. Page B is database update page.
Page A --> Page B -->Page C

Should I add [if] and [bounce] tags on Page B?
What is the best way of Interchange ?

Thanks
