What web framework and other middlewares are you running? Are you using Rack::Head to generate HEAD responses or something else? > 204.93.223.151, 10.195.114.81 - - [11/Aug/2011 21:03:50] "GET / > HTTP/1.0" 200 37902 0.5316 > app error: Content-Length header was 37902, but should be 0 > (Rack::Lint::LintError) > /mnt/data/tanga/current/bundler/ruby/1.9.1/gems/rack-1.2.3/lib/rack/lint.rb:19:in > `assert' > /mnt/data/tanga/current/bundler/ruby/1.9.1/gems/rack-1.2.3/lib/rack/lint.rb:501:in > `verify_content_length' Looking at the 1.2.3 rack/lint.rb code, it should've set @head_request to true when env["REQUEST_METHOD"] == "HEAD" (rack/lint.rb line 56). Do you happen to have any middlewares that might rewrite REQUEST_METHOD? I would edit rack/lint.rb and put some print statements to show the value of @head_request and env["REQUEST_METHOD"] -- Eric Wong _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
