I'm using Rails 3.2.19 with Unicorn 4.8.3 in development on Cloud9 and it suddenly stopped to serve well some javascript files (e.g.: jquery/bootstrap).
The error in Chrome console for those files is:
Failed to load resource net::ERR_CONTENT_LENGTH_MISMATCH
I have this configuration in config/application.rb:
config.assets.enabled = true
config.assets.version = '1.0'
config.assets.initialize_on_precompile = false
And this in my config/environments/development.rb:
config.assets.compress = false
config.assets.debug = true
It seems that there is an extreme odd bug on Cloud9 in which the internal C9 Proxy truncates the HTTP Response randomly. I will post again in the future when the C9 bug is fixed.
