page caching using public/cache directory

[backbonedesign]

I would like to move my cached pages to public/cache/ so I can easily
delete all of my pages when I make a change to my application.

See: http://www.railsenvy.com/2007/2/28/rails-caching-tutorial#moving

But since Passenger doesn't use the .htaccess file, Apache is unable
to see the cached pages.

Any ideas how I can get this to work?

You can enable .htaccess support by setting RailsAllowModRewrite to On.

What are the consequences in Passenger with RailsAllowModRewrite
enabled?

Can you please elaborate on "rewrite rules to negate its effects" in
the below sentence in the docs?
"But please note that you will have to delete Rails applications'
default .htaccess file, or add rewrite rules to negate its effects."

The default Rails .htaccess forwards all requests to
dispatcher.cgi/dispatcher.fcgi, thereby bypassing Passenger unless
RailsAllowModRewrite is on. Make sure that requests are not forwarded to
dispatcher.cgi/dispatcher.fcgi, and you'll be fine.

I was able to use public/cache on passenger 1.9.0 by adding this to my
vhost conf file:

RewriteEngine On
RewriteRule ^([^.]+)$ /cache/$1.html [QSA]

Note: the leading slash was needed on suse/apache (it is not included
in many 'helpful' blogs).
Note: I did NOT need to use: RailsAllowModRewrite on. It didn't seem
to make a difference. I did not do any performance comparisons.

I tried these entries in the .htaccess file, but they were not
recognized/utilized. I attempted this with & w/o
RailsAllowModRewrite.

I hope this helps,

Just to be clear...
When the above mentioned rewrite entries didn't work in .htaccess
(those were the only entries), I deleted the .htaccess file.

Here is my conf:
<VirtualHost *:80>
ServerName myapp.example.com
DocumentRoot /path/to/myapp/current/public


<Directory /path/to/myapp/current/public>
Order Deny,Allow
Allow from all
</Directory>

## tell passenger to allow apache rewrite rules (seems to be
optional as of 06/11/08)
RailsAllowModRewrite on

RewriteEngine On
## Uncomment for rewrite debugging
#RewriteLog /path/to/myapp/current/log/rewrite_log
#RewriteLogLevel 9

#apache should serve cached pages

RewriteRule ^([^.]+)$ /cache/$1.html [QSA]

#*************************
# SVN
# this not only blocks access to .svn directories, but makes it
appear
# as though they aren't even there, not just that they are forbidden
<DirectoryMatch "^/.*/\.svn/">
ErrorDocument 403 /404.html
Order allow,deny
Deny from all
Satisfy All
</DirectoryMatch>

</VirtualHost>

FWIW, if you're using Capistrano, you can use this:

set :copy_strategy, :export

to use "svn export" vs "svn checkout". That way you won't have to
supply a directive to handle them...

Thanks Matt. Unfortunately I only have access to the .htaccess file
(please prove me wrong) since it is being hosted on a shared server at
dreamhost.
