I have new UI setup and noticing that when ever I update a page it is not refreshing with the updated changes. I do not see either the page_{sessionId/GUID}.aspx created either.

Checked the session preview DB and I see the changes in PAGE_CONTENT table with new rendered content, so seems like session preview is working fine but the Preview site is not able to get the changes and refresh the UI.

I have checked all the preview handlers and mappings for .aspx and made sure they are correct in web.config. Any thoughts on why the preview site not showing up the changes?

I have the session preview DB setup in cd_storage_conf.xml.

<StorageBindings>
  <Bundle src="preview_dao_bundle.xml"/>
</StorageBindings>
<Wrappers>
  <Wrapper Name="SessionWrapper">
    <Timeout>120000</Timeout>
    <Storage Type="persistence" Id="db-session-webservice" dialect="MSSQL"
             Class="com.tridion.storage.persistence.JPADAOFactory">
      <Pool Type="jdbc" Size="5" MonitorInterval="60" 
            IdleTimeout="120" CheckoutTimeout="120" />
      <DataSource Class="com.microsoft.sqlserver.jdbc.SQLServerDataSource">

        <Property Name="password" Value="pwd" />
      </DataSource>
    </Storage>
  </Wrapper>
</Wrappers>

PageHandler - The session wrappers are correctly installed.

Any thoughts/pointers on what might be going wrong...? (sorry for the long post)
