Subject: [ruby-core:70680] [Ruby trunk - Bug #11268] [Assigned] Zlib::DataError: incorrect header check

Issue #11268 has been updated by Tomoyuki Chikanaga.

Status changed from Open to Assigned
Assignee set to Akira Tanaka

Yasuhiro, thank you for your investigation!
So is it server side issue?

Anyway, you can specify request header via open-uri.

   require "open-uri"
   open('https://www.hoveround.com', "Accept-Encoding" => "plain") do |f| puts f.read end

This works fine on my environments.
