Apache::Stage - Manage A Staging Directory
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
# this location is served by normal apache. It's recommended to
# restrict access to this location to registered authors of this
# site, but a restriction isn't necessary
ErrorDocument 403 /stage-redir
ErrorDocument 404 /stage-redir
# the name of this location must match the ErrorDocument redirects
# above
# PerlSetVar apache_stage_regex " ^ (/STAGE/[^/]*) (.*) $ "
# This regex has to split a staged URI into two parts. It is
# evaluated with the /ox switch in effect, so this will NOT be a
# per-directory variable. The first part will be thrown away and
# just the second part will be served if the original URI cannot
# be accessed. In case of 301 and 302 redirects the first part
# will be prepended again. The default regex is defined as above
# which means that URIS will be split into "/STAGE/anyuser" and
# the rest.

A staging place is a place where an author of an HTML
document checks the look and feel of a document before
it's uploaded to the final location. A staging place
doesn't need to be a separate server, nor need it be a
mirror of the "real" tree, and not even a tree of symbolic
links. A sparse directory tree that holds nothing but the
staged files will do.
Apache::Stage implements a staging directory that needs a
minimum of space. Per default the path for the per-user
staging directory is hardcoded as
/STAGE/any-user-name
The code cares for proper internal and external redirects
for any documents that are not in the stage directory
tree. This means that all graphics are displayed as they
will be later after the staged files will have been
published. The following table describes what has been

tested:
Location Redirect to Comment
/STAGE/u1/ / Homepage. Internal Redirect.
/STAGE/u2/dir1 /dir1/ Really /dir1/index.html
/STAGE/u3/dir2 /dir2/ Directory has no index.html
Options Indexes is off, thus
"Forbidden"
/STAGE/u4/dir2/foo /dir2/foo Internal redirect.
/STAGE/u5/bar - Exists really, no redirect
necessary
/STAGE/u6 - Fails unless location exists
The entries described in SYNOPSIS in the access.conf or an
equivalent place define the name of the staging directory,
the name of an internal location that catches the
exception when a document is not in the staging directory,
and the regular expression that transforms the staging URI
into the corresponding public URI.
With this setup only ErrorDocument 403 and 404 will be
served by Apache::Stage. If you need coexistence with
different ErrorDocument handlers, you will either have to
disable them for /STAGE or integrate the code of
Apache::Stage into an if/else branch based on the path.
