Now you have a system which has popup modals for editing row level data. On cancelling the pop-up modal, you are back at the previous page. However, on clicking browser back button, the edit popup modal pops up. Which is clearly not the flow of screens you would like. So to avoid that, you can use interceptors to avoid cache memory to store URLs which you do not want to be navigated back.
So, lets say you have a main page: itemManagement.jsp and on edit, the URL is itemManagement/edit.html. edit.htl opens up teh pop-up modal. On cancelling that, if you press back button, you would like to skip edit.html. You can do so by simply adding interceptors in spring config file:
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="itemManagement/edit.html/*"/>
<mvc:mapping path="itemManagement/edit.html"/>
<bean id="webContentInterceptor" class="org.springframework.web.servlet.mvc.WebContentInterceptor">
<property name="cacheSeconds" value="0"/>
<property name="useExpiresHeader" value="true"/>
<property name="useCacheControlHeader" value="true"/>
<property name="useCacheControlNoStore" value="true"/>
</bean>
</mvc:interceptor>
</mvc:interceptors>
Thats pretty much it. Now on clicking back or forward buttons, edit screen does not pops up again, because you have disabled cache storing for this URL. Your browser depends on cache to navigate back and forward to pages but if you disable cache, those pages are skipped while browsing back or forward from your browser's navigation.
