[xwiki-devs] [PROPOSAL] Use relative URLs instead of external URLs with sendRedirect

Hi devs, In HTTP specifications a redirect is always absolute URL which is probably why we use absolute URL with sendRedirect. However sendRedirect does not produce direct HTTP response but allows relative URL and delegate to the application server the job of producing proper absolute URL. IMO XWiki should always use relative URL everywhere it can so I propose to change our practice to use relative URL instead of absolute URL with HttpSevletResponse#sendRedirect when possible. The only reasons I see to use external URLs are: * interwiki URL in a domain based multiwiki * html/pdf export for links pointing on not exported pages or non view actions WDYT ? Here is my +1. We very often fix bugs in the way to produce external URL and it's still not OK (see http://jira.xwiki.org/browse/XWIKI-7632) so lets reduce the scope for this need as much as possible. -- Thomas Mortagne
