How to make an HTTP GET with modified headers?

Question

What is the best way to make an HTTP GET request in Ruby with modified headers?

I want to get a range of bytes from the end of a log file and have been toying with t

Answer 1

Created a solution that worked for me (worked very well) - this example getting a range offset:

require 'uri'
require 'net/http'

size = 1000 #the last offset (for the range header)
uri = URI("http://localhost:80/index.html")
http = Net::HTTP.new(uri.host, uri.port)
headers = {
    'Range' => "bytes=#{size}-"
}
path = uri.path.empty? ? "/" : uri.path

#test to ensure that the request will be valid - first get the head
code = http.head(path, headers).code.to_i
if (code >= 200 && code < 300) then

    #the data is available...
    http.get(uri.path, headers) do |chunk|
        #provided the data is good, print it...
        print chunk unless chunk =~ />416.+Range/
    end
end
