Rack 2.0 dependency

[tycooon]

Hi, why is rack required for this gem? It can be used without web app at all, right? I have problems with some legacy app:

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    httplog (= 1.0.1) was resolved to 1.0.1, which depends on
      rack (~> 2.0)

    sprockets (~> 2.11.0) was resolved to 2.11.3, which depends on
      rack (~> 1.0)

It's using Rack to decode HTTP status codes - see #46. Admittedly it could be done without. I'll see if I can make it less strict, it should work with Rack v1. Stay tuned.

I've loosened the dependency to rack >= 1.0. Could you give it a try from master, and if that solves your issue, I'll release it as a version bump?

It works, a new release would be cool!

By the way, it looks like some of gemfiles are missing in repo (http3 and rack2) and it's strange to me that travis is not complaining about that.

They were still cached on Travis I assume. I added them back (was hoping I don' need to version that's in Gemfile.lock, but no dice).

v1.0.2 released.
