Pages of type "Link to another page in the current site" does not work as expected:They will return the content of link destination instead return a 302 Redirect.

Steps to Reproduce

1. Open a liferay site
2. Add a page called "page1" of type: "2 Columns (30/70)"
3. Add a page called "page2" of type: "Link to a Page of This Site" and link to previous "page1"
4. Add a page called "page3" of type: "Link to a Page of This Site" and link to previous "page2"
5. Open "page2":
   1. Expected behaviour: The request is redirected to page1:
      1. At navigator URL changes from page2 to page1
      2. With developer tools you can see that page2 returns a 302 Redirect to page1
   2. Actual behaviour: page2 returns the content of page1:
      1. The navigator URL remains at page2 without changing to page1
      2. With developer tools you can see that no 302 Redirect is return
6. Open "page3":
   1. Expected behaviour: The request is redirected to page2 and after is redirected again to page1:
      1. At navigator URL changes from page3 to page2 and after to page1
      2. With developer tools you can see that page3 returns a 302 Redirect to page2 and page2 returns a 302 Redirect to page1
   2. Actual behaviour: A error page generated by navigator is shown
      1. The navigator URL remains at page3, showing a error page with "Content Encoding Error" message (Firefox) or "This webpage is not available" ERR_CONTENT_DECODING_FAILED (Chrome)
      2. With developer tools you can see that a 404 Not Found is return with no content
