String representation of the headers to be sent in the response.

# File lib/thin/response.rb, line 29

persistent!() click to toggle source

Tell the client the connection should stay open

# File lib/thin/response.rb, line 93

Persistent connection must be requested as keep-alive from the server and have a Content-Length, or the response status must require that the connection remain open.

# File lib/thin/response.rb, line 100
def persistent?
  (@persistent && @headers.has_key?(CONTENT_LENGTH)) || PERSISTENT_STATUSES.include?(@status)
end
