How to reproduce

• Go to the front-office
• Access a page which contains a form with method POST (front-office search service, directory search service, ...)
• Fill in the form and submit

Actual behavior
The URLs on the new page are invalid as they contain the cms context (http://site.server/cmscontext/fr/page.html)

Expected behavior
The URLs on the new page are valid (http://site.server/fr/page.html)
