  and context document root (which is the file system directory that
  this URL prefix is mapped to). This generalization of the document
  root makes it easier for scripts to create self-referential URLs and
  to find their files.
- Expose CONTEXT_DOCUMENT_ROOT and CONTEXT_PREFIX as envvars, in mod_rewrite,
  and in ap_expr.
- Make mod_alias and mod_userdir set the context information.
- Allow to override the document root on a per-request basis. This allows
  mass vhosting modules to set DOCUMENT_ROOT correctly.
- Make mod_vhost_alias set the per-request document root

Remaining tasks:
- Use the context document root & prefix in mod_rewrite to make RewriteBase
  unneccessary in many cases. Do this without breaking compatibility.
- Write docs.

This is a module developed by myself to support the
RedHat OpenShift Express project, to allow for dynamic
and fast reverse-proxy switching.

The idea is to easily map Host: header entries to
backend servers, with the mapping done in a DBM file
(think of mod_vhost_alias, kinda, for mod_proxy).
Yeah, mod_rewrite and RewriteMap could kinda do
it but (1) that is slow and (2) no support for
ProxyPassReverse capability.

Donated to the ASF.

end_generation is implemented completely by core using the
child_status hook run by the MPM.

simple and mpmt_os2 MPMs don't currently run the child_status
hook, so neither hook is invoked with those MPMs.
