: start {|http| .... }
|
|
|
|
creates a new Net::HTTP object and starts HTTP session.
|
|
|
|
|
|
|
|
When this method is called as iterator, gives HTTP object to block
|
|
|
|
and close HTTP session after block call finished.

|
|
|
get data from "path" on connecting host.
|
2000-03-26 03:48:15 -05:00
|
|
|
"header" must be a Hash like { 'Accept' => '*/*', ... }.
