I know that we can use config.exception_app to set up custom exception
handling and also use rescue_from. However, I have an issue that there is
malformed request (testing generated request) that caused Rails Rack
middleware to throw an exception when Rack''s parse_query method. Here is
the detail of the

Rack middleware for shared connection pools?
I have a Rails app that makes connections to other DBs. There may be
multiple users connecting to multiple DBs.
The app makes a database connection as part of an action. However, I
noticed a problem: there's too many DB connections remaining open, which is
causing the DB to not have enough connections remaining for new connections.
So the answer is using a shared connection pool.

rspec-rails and rack middleware
It doesn''t seem like my controller specs are calling my middleware on
requests. Has anyone figured out a good way to test middlware with rspec?
I''m thinking something like
rails'' rails/actionpack/test/controller/session/mem_cache_store_test.rb but
with rspec... any thoughts?
Thanks!
Best,
Aaron

Rack, Camping 2.0++
===
1. Camping on Rack
===
I''ve just finished rewriting Camping to use Rack in the "core". I got rid of
(a little less) than 1kB in camping.rb and removed lots of un-necessary files
(lib/server/*.rb, fastcgi.rb & mongrel.rb).
bin/camping does now only provide WEBrick, Mongrel and console-support and
should only be used in development. It uses Rack::ShowExceptions to catch

Hi there - I''m a ruby newbie and am stuck on the Getting Started with Rails

request.format = :mobile causes error "undefined method `ref' for nil:NilClass"
I have a strange problem with setting request.format = :mobile
I can reproduce this problem on a completely fresh Rails 3.0.7 app
with no special gems. This seemed to work well in Rails 2 but for some
reason is hiccuping here, not sure what''s different in Rails 3 that
makes this hiccup. If you look at the stack track, it doesn''t even
pass through my app stack once -- weird --
