Rails - Mar 2008 - Apache + mongrel cluster: early unescaping of URI by Apache

Hello all,

I have run into a weird problem.

I have the following route:

map.show_wiki_page  ''wiki/show/:name/:version'', :action =>
''show'' , :version
=> nil, :requirements => {:version => /\d+/, :name => /[\d
\w\?\!,\(\)\[\]]+/}

If I run a bare mongrel (my dev environment) and access my app with
http://myhost/wiki/show/Waarom+deze+wiki+%3F%3F,
my params are {"name"=>"Waarom deze wiki ??",
"action"=>"show",
"controller"=>"wiki"}, which is exactly what I expect,
but
in my production environment (apache 2.2.3 + mod_proxy + mongrel cluster) my
params hash is
{"name"=>"Waarom deze wiki ",
"action"=>"show",
"controller"=>"wiki",
"?"=>nil} which is incorrect.

Looking into request headers here''s what I have found out:

Bare mongrel:

"REQUEST_URI"  =>"/wiki/show/Waarom+deze+wiki+%3F%3F"
"PATH_INFO"    =>"/wiki/show/Waarom+deze+wiki+%3F%3F"
"REQUEST_PATH" =>"/wiki/show/Waarom+deze+wiki+%3F%3F"


Apache + mongrel cluster:

"REQUEST_URI" =>  "/wiki/show/Waarom+deze+wiki+??"
"PATH_INFO"    => "/wiki/show/Waarom+deze+wiki+"
"REQUEST_PATH" => "/wiki/show/Waarom+deze+wiki+"

Looking at REQUEST_URI of the production environment I am wondering why
Apache unescaped the URI before sending
it to mongrels.

The rewriting rule is standard and used by other similar setups, as far as I
know:

# Redirect all non-static requests to cluster
 RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
 RewriteRule ^/(.*)$ balancer://portal_cluster%{REQUEST_URI} [P,QSA,L]

Does anyone have similar experience? Where should I be looking to change
this behavior?

Thank you!

Production box: Debian stable
Mongrel 1.1.1
Rails 1.2.5
apache 2.2.3

Best regards,
Yuri Leikind

we had a similar issue which i gladly solved today. here''s what i
needed to change to make it work:
<http://prometheus.khi.uni-koeln.de/trac/pandora/changeset/555>

see the references there for more information; particularly,
<https://issues.apache.org/bugzilla/show_bug.cgi?id=34602#c16>.
