Sling mapping multi language site

Hi,

I've tried searching the forum, but did not find an answer to my question.

We have a multi language site, with two languages English and Spanish.

Our site structure is as follows:

content

     |----mysite

               |-------es

                         |----... (spanish pages)

               |-------en

                         |----... (english pages pages)

The default urls are something like this:

    www.myhost.com/content/mysite/en/welcome.html

By using sling mappings I would like to become the following:

   www.myhost.com/en/welcome.html

So get rid of the /content/mysite/ part en keep the locale.

Using the following sling mapping, I am able to get rid of the /content/mysite/en part

<?xml version="1.0" encoding="UTF-8"?>

<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"

    jcr:primaryType="sling:Mapping"

    sling:internalRedirect="[/content/mysite/en/(.*)]"

    sling:match="www.myhost.com/$1"/>

The link checker (transformer) rewrites the menu links to:

   www.myhost.com/welcome.html and these links work.

But when I want to keep the locale, with the following mapping:

<?xml version="1.0" encoding="UTF-8"?>

<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"

    jcr:primaryType="sling:Mapping"

    sling:internalRedirect="[/content/mysite/(.*)]"

    sling:match="www.myhost.com/$1"/>

I get links like this: www.myhost.com/en/welcome.html, but these result in a 404.

The log shows the following message:

GET /content/mysite/en/en/welcome.html HTTP/1.1] org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Resource /content/mysite/en/en/welcome.html not found

Somehow the locale is duplicated now.

Can someone explain me what I'm doing wrong ?

Thanks for your help!
