Subject: Questions about the Prohibition of String Subclasses in responses

Message-ID: <b757a8ed-f2b0-4731-b4f4-50f80e58e47a@v15g2000prn.googlegroups.com> (raw)
Hey Guys,
As I prepare to merge the new on-by-default XSS protection into rails
I'm bumping up against a constraint in rack, and I'm having trouble
figuring out why it's there.
http://github.com/chneukirchen/rack/blob/master/lib/rack/lint.rb#L465-475
Our XSS safe responses will fail this test because they return an
instance of ActionView::SafeBuffer which is a subclass of String. We
use a subclass so that we can make all the concat and append
operations escape their arguments.
What's the rationale for preventing me from sending a subclass of
string? Can we just change this stuff to use Object#kind_of? instead?
Cheers
Koz
