  1. POJSF 2 : How to make browser back button not to used cache pages and make a kind of refresh/redirection?
    text
    copied!<p>I use JSF 2.2 &amp; prettyfaces. I want to prevent security problems linked to browser backward functionality.</p> <p>To resume the navigation link between my pages in my application : I have a login page done with Spring Security which redirects after connexion to a HomePage. The HomePage is in ViewScoped. From this HomePage , i can go to a AddPatientPage in ViewScoped and a AddAnalysePage in SessionScoped.</p> <p>When the user is on the AddP*Page, if he clicks the browser backward button, i don't want to use cached page. I want a kind of redirection/ refresh of the page. I want the Homepage to use the initial values as it was a first load.</p> <p>I'm trying to apply this <a href="https://stackoverflow.com/questions/10305718/avoid-back-button-on-jsf-web-application?lq=1">solution</a> without success... For example, when i get back to the HomePage from Add*Page, the values from the SelectOneMenu are not the initial ones, but the last selectioned. So i believe the cash is still use... Before to test , i cleared the cache files from browser.</p> <p>Thanks for the help.</p> <p>As BalusC in previous Post, i don't use annotation but directly referencing the filter in web.xml as above.</p> <pre><code>&lt;filter&gt; &lt;filter-name&gt;noCacheFilter&lt;/filter-name&gt; &lt;filter-class&gt;com.clb.genomic.lyon.servletFilter.NoCacheFilter&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;noCacheFilter&lt;/filter-name&gt; &lt;url-pattern&gt;*.jsf&lt;/url-pattern&gt; &lt;url-pattern&gt;*.xhtml&lt;/url-pattern&gt; &lt;/filter-mapping&gt; </code></pre> <p><strong>* EDIT :*</strong> </p> <p>Using different words ,the problem is that when i use the backward button the values of the page components are not the same that its backing bean. So i don't understand which are kept tracked and which ones are not in the scope.</p> <p><strong>* EDIT2 :*</strong> </p> <p>Ok , i let down the ajax call. The idea of the ajax call was that when you select a value in SelectOneMenu from a first form , you then inject the result to and other form with a second another SelectOneMenu and a commandButton to send all the values together. That was a mess to handle with backward button compatibility. So now i put the two selectOneMenu, in an unique form without ajax and it's working well...no problem with backward button and synchronisation between beans &amp; page values of SelectOneMenu...</p> <p>I hope someone have understand what was i trying to do :)</p>
