Rails - Jan 2006 - Routing problems - Apache proxy vs. Webrick direct

I dropped the use of fastcgi because I could not get popen working (see 
''[Rails] Apache2 and popen'').  It works under WebBrick.  Since
CGI is too
slow, I thought I''d proxy to WebBrick via Apache.

I am having routing problems now with escaped slashes in the URL.

Here''s my routes.rb:
  map.connect '''', :controller => "wiki"
  map.connect '':controller/service.wsdl'', :action =>
''wsdl''
  map.connect '':controller/:action/:id''

My request should drop down to the default action.

Here''s my apache vhost configuration:

#    ProxyPass / http://localhost:3000/
#    ProxyPassReverse / http://localhost:3000/
    RewriteEngine On
    ProxyPreserveHost On
    RewriteRule ^/(.*) http://localhost:3000/$1 [P,L]

I''ve tried both above, what I have commented out and what I have
uncommented
with the same results below.

Here''s the url I request and the not found error in the apache logs:
10.0.0.2 - - [06/Jan/2006:02:49:19 -0500] "GET 
/repository/index/lib%2Fnet%2F HTTP/1.1" 404 618

And here''s the error in my rails log:

It looks like all the params are empty????


Accessing the same URL, except bypassing Apache and using the Webrick port I 
get success:

Processing RepositoryController#index (for 10.0.0.2 at 2006-01-06 03:04:26)

How do I fix this?

Hi Jon,

I am not very familiar with mod_rewrite but maybe adding QSA to the
rule will help?

>     ProxyPreserveHost On

RewriteRule ^/(.*) http://localhost:3000/$1 [QSA, P,L]

As a side note: I have found lighttpd faster and more reliable than
webrick for development. And I am using proxying Apache -> Lightttpd
setup on my Textdrive account - it works like a charm.

Thanks.  I gave that a shot but I still get the same errors.

I should add that I am having no trouble at all with other controllers in 
this same application using the Apache proxy to webbrick.

The main difference with this particular controller is the escaping of
/''s
in the :id part.

/repository/index/lib%2Fnet%2F

Looks like it''s a mod_rewrite bug.
http://issues.apache.org/bugzilla/show_bug.cgi?id=34602

And it''s also a Proxypass bug
http://issues.apache.org/bugzilla/show_bug.cgi?id=29554

It''s only been broken for a year and a half.

I guess I have to reevaluate how to do this.

I''d like to pass a path to :id.  Maybe use separators that
won''t be stepped
on by
apache?

I thought I post my solution in case anyone else encounters this.

I rewrote application.

In routes.rb..

  map.connect '''', :controller => "wiki"
  map.connect ''repository/index/*path'', :controller =>
"repository", :action
=> "index"
  map.connect ''repository/show/*path'', :controller =>
"repository", :action
=> "show"
  map.connect '':controller/service.wsdl'', :action =>
''wsdl''
  map.connect '':controller/:action/:id''

I pass the rest of the parms in an array. Can''t use *id for some reason
above.

Looks like this when the controller gets it.
Parameters: {"action"=>"index",
"controller"=>"repository",
"path"=>["lib",
"net"]}

Also in my views, I couldn''t stuff the path into :id nor :path and use 
link_to.  I expect
:path gets walked on by the routing code above.

So I had to create me own links.
<%= "<a href=\"/repository/index/#{@fpath.empty? ? "":
@fpath+''/''}#{f[0...-1]}\">#{f}</a>" %>
