Apache proxypass messes up my link_to's

Hey all,

Ive got some heavy restrictions on a site I'm building. I have to serve my rails app from a different machine than my web server. The webserver *must* use apache, and I cant muck with its configuration too much, other than to modify the httpd.conf file a bit. I don't know much about Apache, but I found a little gem called proxypass that seemed to get me a little closer to the final solution. The rails server machine is completely configurable by me, so that's the good news.

I used Apache proxypass and proxypassreverse in order to be able to access my rails machine like so: http://thewebserver.com/myapp/controller/action/id. This works fine, except all of my link_to's and redirect_to's are now 404s as they point straight to http://thewebserver.com/controller/action/id.

Am I missing something? I may be misusing proxypass for all I know. I was hoping some of y'all had come across something like this before. The bottom of my httpd.conf looks like this:

ProxyPass /myapp/ http://myrailsserver:3000/ ProxyPass /myapp http://myrailsserver:3000/ ProxyPassReverse /myapp/ http://myrailsserver:3000/

I'm using webrick as the http server for rails for now, but plan to move to mongrel once I get this solved.

Thanks in advance,

John

You should put the following line in environment.rb: ActionController::AbstractRequest.relative_url_root = '/myapp' I once documented this at <http://wiki.rubyonrails.org/rails/pages/HowtoSetupApacheProxyingToLighttpdWithFastCGI&gt;\. That wiki entry was written for Lighttpd, but the relative_url_root part works with webrick too.

Your directory structure should be something like this..

/public_html   /myapp --> /any/path/public   [other live files]

/any/path/app /any/path/components [...] /any/path/public [...]

I.e. use a symlink to the Rails public directory, which can be anywhere on the machine (ideally not in a web-accessible directory)

Then, the rails helpers will all work as you expect, automatically.
