Setting HTTP response headers application-wide in Rails 3.2 -


how set response headers application-wide in rails 3.2?

the rails guides security 4.0 mentions config.action_dispatch.default_headers:

8 default headers

every http response rails application receives following default security headers.

config.action_dispatch.default_headers = {   'x-frame-options' => 'sameorigin',   'x-xss-protection' => '1; mode=block',   'x-content-type-options' => 'nosniff' }

you can configure default headers in config/application.rb.

config.action_dispatch.default_headers = {   'header-name' => 'header-value',   'x-frame-options' => 'deny' }

but couldn't find application-wide configuration of headers in security guide rails 3.2, or relevant in configuring guide rails 3.2. answers in how add custom http header? seem either addressing versions of rails more recent 3.2, or modify responses in controllers rather application wide.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
