Malformed Update URI

[adamgotterer]

I'm trying to run auto update from a ruby-packer app but have been running into a malformed uri error on multiple webservers I tested on. I logged the request to a very basic webserver which looks like:

HEAD  HTTP/1.0
Host: localhost

I believe this request is missing a / between HEAD and HTTP/1.0 and the port appears to be missing from HOST. A well formed request generated from CURL looks like:

HEAD / HTTP/1.1
Host: localhost:9292
