Hi.

I'm trying to sort out expires headers for my rails app.

I'm trying two approaches, neither of which seem to work:

---------- Approach 1 - (simple expires in if block):

location / {

if ( $request_uri ~* \.(css|js|gif|jpe?g|png|ico|htc)\?ts_ ) { expires max; }

if (-f $request_filename) { break; }

proxy_pass http://app_servers; }

This doesn't work at all unless I put a break; within the if block (same problem as: http://www.ruby-forum.com/topic/129953)

---------- Approach 2 - (set expires variable into a variable):

location / { set $expires_value -1;

if ( $request_uri ~* \.(css|js|gif|jpe?g|png|ico|htc)\?ts_ ) { set $expires_value max; }

if (-f $request_filename) { expires $expires_value; break; }

proxy_pass http://app_servers; expires $expires_value; break; }

This gives me an emerg message: "expires" directive invalid value in conf_file

Can anyone help with this? Thanks, Rob
