Submitted some comments. Looks good!

Some of the SSL form options either need params[:ssl]&.dig(...) or we could assign ssl_params = params.fetch(:ssl,{}) in the route and use ssl_params[...] in the form.

Hmm, I may have merged a little too quickly. I think this code is slightly incorrect. It should parse the String by each line, then split the line by /:\s*/, then possibly check if the value part contains , to split the value by , .

We also probably want to support repeated multiple headers:

X-Foo: value1
X-Foo: value2
X-Bar: value3

{"X-Foo"=>["value1","value2"], "X-Bar"=>"value3"}
