REST + Caching + Apache 2.2 Rewrite problem and solution?

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?

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