FS#2315 subdomain to namespace mapping (address rewriting)

2011-08-21 steelman

I have registered a domain, example.eu (I haven't but let's assume that for a moment). I have set up a wildcard support on a webserver so all requests for any resource in any of subdomains are handeled by the same DOCUMENT_ROOT.

-----
DOCUMENT_ROOT
+ .htaccess
+ blog-files/
+ doku/
\ wiki-files/
\ robots.txt
-----

I would like to have a wiki and a blog, available as wiki.example.eu and blog.example.eu, respectively. So I've installed DW in DOCUMENT_ROOT/doku and created .htaccess like this:

-----
RewriteCond %{HTTP_HOST} !=wiki.example.eu
RewriteRule .* - [S=3]
# let's ommit al the _media, _export stuff for the sake of simplicity

# some static files, eg. http://wiki.example.eu/robots.txt
RewriteCond %{DOCUMENT_ROOT}/wiki-files/%{REQUEST_URI} -f
RewriteRule (.*) /wiki-files/$1 [L]

RewriteRule ^$ /doku/doku.php?id=wiki/start [L]
RewriteRule (.*) /doku/doku.php?id=wiki/$1 [L]

RewriteCond %{HTTP_HOST} !=blog.example.eu
RewriteRule .* - [S=3]

RewriteCond %{DOCUMENT_ROOT}/wiki-files/%{REQUEST_URI} -f
RewriteRule (.*) /blog-files/$1 [L]

RewriteRule ^$ /doku/doku.php?id=blog/start
RewriteRule (.*) /doku/doku.php?id=blog/$1
-----

With a setup like this http://blog.example.eu/2011-08-21/a_post becomes http://blog.example.eu/doku/doku.php?id=2011-08-21/a_post and http://wiki.example.eu/ is in fact http://wiki.example.eu/doku/doku.php?id=wiki/start. In the local.php file I set different configuration values (template etc.) depending on $_SERVER['HTTP_HOST']

-----BEGIN FEATURE REQUEST-----
I would like DokuWiki to offer yet another 'userewrite' option (let's call it 1a, because IMHO it requires .htaccess) that could use some kind of association between values of HTTP_HOST and namespaces (basens for each known HTTP_HOST?) and would provide links with the chosen namespace stripped. This applied to _media, _detail and _export too.
-----END FEATURE REQUEST-----

I've tried to frob basedir but it occurs that it introduces problems with "support" scripts (eg. css.php, fetch.php) still need to be accessed as http://wiki.example.eu/doku/lib/exe/css.php.

This is not exactly what you asked for, but... Are you aware of farms? => http://www.dokuwiki.org/tips:farm

Yes I am. Unfortunately I can't create symlinks on the server I use (I understand that in a shared virtual hosting environment symlinks may be a security issue).

BTW. Is it possible to reconfigure where DW keeps data ("data/" directory)? If so then this might (I havn't tried it) be a solution.

-----
DOCUMENT_ROOT
+ .htaccess
+ blog-files/
\data
+ doku/
\ wiki-files/
+ data
\ robots.txt

1. You don't need symlinks for farms. (There is a symlink approach, but that is on a different wiki page.)
2. It has always been possible to move the data directory somewhere else ($conf['savedir']). That's one of the key elements how a farm works.
3. Ergo, please read that farm page again.

With this additional info about the farm it is solved?

This can be solved without symlinks.
