Ruby Forum Ruby on Rails > REST + Caching + Apache 2.2 Rewrite problem and solution?

Hi,

A lot of us are now using Apache 2.2 + mod_rewrite to forward incoming 
and uncached requests to a Mongrel Cluster.

That was fine until REST arrived.

With the current recommended configuration, Apache works as follows:

a. There is a static file avaliable in the file system => send it 
(regardless to the request method)
b. There is none, forward request to Mongrel Cluster

However, with RESTful Rails, we have urls such as /articles/1 which 
should be cached only when we GET it, not when we POST or PUT it. What 
if we want to update an article and Apache sends us the static HTML file 
instead of forwarding our request to Rails?

Here is the solution I suggest:

Replace in apache configuration file:

  # Redirect all non-static requests to cluster
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
  RewriteRule ^/(.*)$ balancer://MyCluster%{REQUEST_URI} [P,QSA,L]

By

  # Redirect all non-static requests to cluster
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f [OR]
  RewriteCond %{REQUEST_METHOD} !^GET*
  RewriteRule ^/(.*)$ balancer://MyCluster%{REQUEST_URI} [P,QSA,L]

What do you thing about that?

>   RewriteCond %{REQUEST_METHOD} !^GET*
>   RewriteRule ^/(.*)$ balancer://MyCluster%{REQUEST_URI} [P,QSA,L]

Does it work?  Seems like it should.  Mongrel has something similar
built in actually (not that it'll help in this case).

Yes it should work. But I am looking for people who know more than I do 
about Apache and REST to confirm that this is or is not a good idea...

Someone?

I spent loooong time to locate the problem, and then your solution
saved me from wasting more. Thanks a lot.
