PrettyFaces kills the session on every request that involves a redirect when the application is deployed on Wildfly 8.1.0.Final. The same app deploys and works properly on Wildfly 8.0.0.Final. 

On 8.1.0 PrettyFaces appears to prevent the servlet stack from retreiving the session ID. 

The log shows no exceptions in either case. The URL rewrites occur, but session information (including login information) is gone. This is my pretty-config.xml

```
<pretty-config xmlns="http://ocpsoft.org/schema/rewrite-config-prettyfaces"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://ocpsoft.org/schema/rewrite-config-prettyfaces
                  http://ocpsoft.org/xml/ns/prettyfaces/rewrite-config-prettyfaces.xsd">

<url-mapping id="user-settings">
    <pattern value="/protected/user/settings/"/>
    <view-id value="/protected/usersettings.xhtml"/>
</url-mapping>

<url-mapping id="thread-edit">
    <pattern value="/protected/threads/edit/#{stitchId}/" />
    <view-id value="/protected/threads/stitch.xhtml" />
    <action>#{stitchEditBean.editStitchFromId(stitchId)}</action>
</url-mapping>

<url-mapping id="threads-index">
    <pattern value="/protected/threads/" />
    <view-id value="/protected/threads/index.xhtml" />
</url-mapping>
</pretty-config>

```

The failure occurs for both PrettyFaces 2.0.12.Final and 3.0.0.Alpha2
