Method: Net::HTTP::Persistent#request

Defined in:
lib/net/http/persistent.rb

#request(uri, req = nil, &block) ⇒ Object

Makes a request on uri. If req is nil a Net::HTTP::Get is performed against uri.

If a block is passed #request behaves like Net::HTTP#request (the body of the response will not have been read).

req must be a Net::HTTPRequest subclass (see Net::HTTP for a list).

If there is an error and the request is idempotent according to RFC 2616 it will be retried automatically.
