I was starting to look at what to modify and I found that we are
really not consistent right now: most of the Java code in oldcore like
XWikiAction are using absolute URL but all VM I could see (and I guess
it's the same for the wiki pages) send relative URLs.
So using absolute URL for send redirect is very far from being a rule
right now. It also mean that making it configurable is going to be a
pain since none of the .vm and wiki page are going though some common
redirect oriented URL generator like most Java code do.
Here is a proposal:
* introduce a configuration but use it only in
XWikiDocument#getURL(String action, String params, boolean redirect,
XWikiContext context) (that's the method where pretty much all Java
code go trough when asking for a redirect URL)
* introduce a api.Document#getURL(String action, String queryString,
boolean redirect) method to follow XWikiDocument (from scratch I think
I would prefer getRedirectURL but it's simpler to follow already
existing API for now)
* we can refactor later the .vm and wiki page to support this new
configuration. What's important right now is to allow someone to come
back to old behavior for whatever reason (which sounds a lot less
necessary to me now that I know that we actually use a lot of relative
URL in sendRedirect) but better be safe since it does not cost a lot
here and I plan to introduce this in xwiki.cfg only
WDYT ?

What problem ? If you are talking about

specific use case as I said on the issue itself.
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 ?
I don't think this will actually solve the problem. As long as XWiki doesn't
know the correct URL to use, I doubt that the container will do any better.
I just tested this on Apache HTTPD + mod_proxy_http going to Jetty, and it
didn't solve the problem.
Probably mean you did not properly configured your reverse proxy but
in my use case it was done right.
For the PDF export, all URLs must be external. A relative URL in a PDF
doesn't have a base URL to work with, since the PDF is a standalone
document. That's why we use a special URLFactory when exporting PDFs.
I know we are using a special URLFactory for pdf export. If a document
pointing to itself or to another document exported in the same pdf is
an external URL with sheme/host/port then there is something pretty
wrong in the pdf export. Anyway that's not really the subject of the
proposal.
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.
