[Moin-devel] [PATCH] Small kluge for easier mod_rewrite integration

[Malte S. Stretz]

And hello again,

as the url_mappings feature didn't do what I intended to do -- have a user 
website transparently fed from a Wiki like <http://example.com/WikiSandBox> 
but only with .htaccess so no ScriptAlias possible -- I tried to tell Moin 
which root it should use.  According to the hack posted in [1] and the 
unanswered question on [2] does one have to do some patching to get that to 
work.

With some black mod_rewrite magic it's possible to feed the script a 
different SCRIPT_NAME; unfortunately does the rewrite process prepend the 
string REDIRECT_ to the environment variable.  The attached patch makes 
moin.cgi use that var if its defined.

This works for me with the following .htaccess:
| RewriteEngine On
| RewriteBase /~mss
| 
| # The *-bin directories (like cgi-bin, wiki-bin, image-bin, ...) shall not
| # be touched by any following rewriting rules.  
| RewriteCond %{REQUEST_URI} /[a-z]+-bin/
| RewriteRule ^ - [last]
|
| # Now the Wiki-rewriting...
| #
| # Strip trailing slashes -- they are good for directories but not for Wiki
| # names.
| RewriteRule ^(.*)/(\?.*)?$ $1$2  [last,redirect=permanent]
| # Transparent access to the Wiki pages; set the SCRIPT_NAME environment
| # variable so moin.cgi know where to link to.
| RewriteRule ^(.*)$ cgi-bin/moin.cgi/$1 [env=SCRIPT_NAME:/~mss]

I guess the even cleaner solution would be to introduce a new config 
variable like wiki_prefix -- but for now the attached solution was easier 
to implement for somebody like me who doesn't know much about Python and 
even less about the MoinMoin internals :)

Cheers,
Malte
