Asp Forum - is this an open-uri bug?

Hi, I'm new to Ruby and new to using open-uri. But I think I found a
bug. Could someone take a look at this and if this is really a bug,
tell me who to report it to?

Thanks,
Todd.

Here's my little code snippet:

====== code starts ======

require 'open-uri'

string =
"http://www.infospace.com/home/redirect.htm?formfr...&p...
ctory&wqhqn=2&qhqn="
string += "Bubba+Ray+Jackson&qc=Broomfield&qs=co"

puts "\nI'm going to try to open this: #{string}\n\n"

#
# This call throws a URI::InvalidURIError. Is that a bug?
# Looking at the error message, I THINK open_uri is following
# a redirection and somehow mis-parsing the new URI such that
# an erroneous space is inserted.
#
uri = open(string)

====== code ends ======

And here's the output:

I'm going to try to open this:

It seems that the URI is redirected to invalid URI.

% ./ruby -ropen-uri -e '
class << URI
alias org_parse parse
def parse(arg)
p arg
org_parse(arg)
end
end
open("http://www.infospace.com/home/redirect.htm?formfrom=qsearch&pgtarg=directory&wqhqn=2&qhqn=Bubba+Ray+Jackson&qc=Broomfield&q...)

Since the last URI

contains a space, URI.parse fails.

I had this problem. My targeted web page is a bit snitty and insisted on
also receiving a user-agent.

myData = open('http://my.target.site&search..., "User-Agent" => "Ruby/#{RUBY_VERSION}" )
myData.each {|x| puts x + '\n'}

I hope this wasn't too late for you to use.
