Subject: [ruby-core:69652] [Ruby trunk - Bug #11281] [Open] Unexpected behaviour in HTTP header processing

Issue #11281 has been reported by John Carter.

----------------------------------------
Bug #11281: Unexpected behaviour in HTTP header processing
https://bugs.ruby-lang.org/issues/11281

* Author: John Carter
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Running this:

Net::HTTP::Get.new('http://any.url', {'header' => nil})

Results in:
NoMethodError: undefined method `strip' for nil:NilClass
	from /home/vagrant/.rvm/rubies/ruby-2.2.2/lib/ruby/2.2.0/net/http/header.rb:17:in `block in initialize_http_header'
	from /home/vagrant/.rvm/rubies/ruby-2.2.2/lib/ruby/2.2.0/net/http/header.rb:15:in `each'
	from /home/vagrant/.rvm/rubies/ruby-2.2.2/lib/ruby/2.2.0/net/http/header.rb:15:in `initialize_http_header'
	from /home/vagrant/.rvm/rubies/ruby-2.2.2/lib/ruby/2.2.0/net/http/generic_request.rb:43:in `initialize'
	from /home/vagrant/.rvm/rubies/ruby-2.2.2/lib/ruby/2.2.0/net/http/request.rb:14:in `initialize'
	from (irb):13:in `new'
	from (irb):13

Suggest implementation changes to assume a nil header value is the same as an empty string.

Thanks,

John
