[Catalyst] RFC for plugin to strip script name from URI; plugin name + code review

[Ashley]

I'm using shared hosting for several Cat deployments. This means I  
can't do nice Location/Apache tricks or lighttpd or modperl. I am  
running fastcgi but I have to deploy it with nothing but mod_rewrite  
at my disposal.

Essentially this is just so that
  - /deploy_dir/myapp.fcgi/cat/path/args

Can always look like
  - /deploy_dir/cat/path/args

And uri_for will correctly drop the script name. It might seem silly  
but it's important so the URI structure will not change if deployment  
changes. I don't like having several versions of the same little hook  
to make it work the way I want so I'm going to do a plugin. I'm asking-

  - What should this be named? Catalyst::Plugin::IhaveNoFreakingIdea...
  - Is the following code and the .htaccess info entirely correct? It  
will serve as the POD examples. What could be better?

I've been using this code in production for a year and a half without  
trouble but that doesn't mean it's right (especially the mod_rewrite  
stuff). So I *really* appreciate any help bomb-proofing it.

  # I think this config stuff can't be done this way in a plugin;
  # have to do a merge or something that I'll have to look up.
  use File::Spec;
  __PACKAGE__->config->{application_executable} = (File::Spec- 
 >splitpath($0))[-1];

  sub uri_for {
      my $self = shift;
      my $uri = $self->NEXT::uri_for(@_);
      my $program_name = $self->config->{application_executable};
      $uri =~ s,/\Q$program_name\E(?=/|\z),,;
      return ref($uri) ? $uri : URI->new($uri);
  }

.htaccess # This one implies a / deployment.
-----------------------
  DirectoryIndex myapp.fcgi index.html

  RewriteEngine on

  RewriteCond %{REQUEST_FILENAME} !myapp.fcgi$
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !(.*[^/])$
  RewriteRule ^(.*)/$ /$1 [QSA,L,R=301]

  RewriteCond %{REQUEST_FILENAME}   !-d
  RewriteCond %{REQUEST_FILENAME}   !-f
  RewriteRule ^(.*) /myapp.fcgi/$1 [QSA,L]


Thanks for looking!
