Method: Mongrel::CGIWrapper#header

Defined in:
lib/mongrel/cgi.rb

#header(options = "text/html") ⇒ Object

The header is typically called to send back the header. In our case we collect it into a hash for later usage.

nph – Mostly ignored. It’ll output the date. connection – Completely ignored. Why is CGI doing this? length – Ignored since Mongrel figures this out from what you write to output.
