apache rewrite help

I'm trying to proxy a server and change the appearance of the server directories for client browsers.

On the proxy server ("proxy"), I've added the following:

Code:

ReWriteEngine On
RewriteRule  ^/dir/ect/ory/$ http://server/directory/ [R]

This works in general, but the browser displays proxy/directory/ instead of proxy/dir/ect/ory/, which is what I would like it to show (is that a transparent proxy?).

I've also had to write additional rules for subdirectories, which tells me I'm probably doing something wrong:

Code:

RewriteRule  ^/dir/ect/ory/subdir$ http://server/directory/subdir [R]

To further complicate things, it doesn't work properly unless I include a ProxyPass directive:

Code:

ProxyPass /directory http://server/directory
ProxyPassReverse /directory http://server/directory

Any thoughts on what I'm doing wrong?

I think a very simple pair of ProxyPass|ProxyPassReverse directives could replace some of this stuff, but not all... what about this on the proxy server:

Code:

ProxyPass /dir/ect/ory http://server/directory
ProxyPassReverse /dir/ect/ory http://server/directory

That seems to do exactly what I need as far as the client-side URL goes.

The problem is the subdirs: I'm doing this because I need to mirror TWiki pages (which are not .HTML files) with their HTML counterparts. The TWiki treats URL space a bit differently (their "webs" and "topics" appear as directories without a trailing slash in the URL). So when you browse to a specific page of the TWiki, you don't append .html to the URL because it doesn't exist. However, it's there on the HTML mirror, and I need something to not ony append the .html suffix to each incoming request, but to be able to tell whether the request is looking for a file or a directory.

The RewriteRule above works for that, if I duplicate it so it appears with and without the trailing slash, and for each subdirectory (I'm sure there's a better way... I can't figure out the syntax to condense it all). But that doesn't help with the URL space issue that ProxyPass seems to help with.

Folks, any ideas on how to get this working, or to improve the methods I've tried? I'd really appreciate your help.

OK... can anyone help me figure out how to clean this up on the proxy's httpd.conf?

Code:

<VirtualHost *:80>
    ServerAdmin webmaster@webserver
    ServerName webserver
    ReWriteEngine On
    RewriteLogLevel 2
    RewriteRule  ^/dir/ect/ory/misc/(\w+)(/.*)$  /directory/$1/misc/$1$2 [P,L]
    RewriteRule  ^/dir/ect/ory/(\w+)/misc(/.*)$  /directory/$1/misc$2 [P,L]
    RewriteRule  ^/dir/ect/misc/(\w+)(/.*)$  /directory/$1/misc/$1$2 [P,L]
    RewriteRule  ^/dir/ect/(\w+)/misc(/.*)$  /directory/$1/misc$2 [P,L]
    RewriteRule  ^/dir/misc/(\w+)(/.*)$  /directory/$1/misc/$1$2 [P,L]
    RewriteRule  ^/dir/(\w+)/misc(/.*)$  /directory/$1/misc$2 [P,L]
    RewriteRule  ^/dir/ect/ory/(\w+)/(\w+).html$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/ect/ory/(\w+).html$  /directory/Main/$1.html [P,L]
    RewriteRule  ^/dir/ect/ory/(\w+)/(\w+)$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/ect/ory/(\w+)/?$  /directory/$1/WebHome.html [P,L]
    RewriteRule  ^/dir/ect/ory/?$  /directory/Main/WebHome.html [P,L]
    RewriteRule  ^/dir/ect/(\w+)/(\w+).html$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/ect/(\w+).html$  /directory/Main/$1.html [P,L]
    RewriteRule  ^/dir/ect/(\w+)/(\w+)$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/ect/(\w+)/?$  /directory/$1/WebHome.html [P,L]
    RewriteRule  ^/dir/ect/?$  /directory/Main/WebHome.html [P,L]
    RewriteRule  ^/dir/(\w+)/(\w+).html$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/(\w+).html$  /directory/Main/$1.html [P,L]
    RewriteRule  ^/dir/(\w+)/(\w+)$  /directory/$1/$2.html [P,L]
    RewriteRule  ^/dir/(\w+)/?$  /directory/$1/WebHome.html [P,L]
    RewriteRule  ^/dir/?$  /directory/Main/WebHome.html [P,L]
    ProxyPass /directory http://webserver/directory
    ProxyPassReverse /directory  http://webserver/directory
</VirtualHost>

It finds all the files and directories, but some of the redirects give screwy URLs, and there's probably a much more efficient way to do all this.

Thanks.
