the examples as are in this branch give an error (the requests produce a 400 error), the code before the change is also not up to date, but let's make sure it all works perfectly before we merge it.
@zmughal can you please share the output you get from running this and the exact command you run the example with?

[mickeyn]

looks like my bad on the 400.
still the output of the examples doesn't look so good.
let's fix that.

[mickeyn]

these changes are ok.
as a follow up we should rework the outputs.

[zmughal]

I don't know if this helps, but Data::Printer has support for pretty-printing various HTTP-related data under Data::Printer::Filter::Web. Might make it easier to follow.

Thanks @zmughal. I did not know about that filter. Are you saying we should use it in some of the examples?

[mickeyn]

Thanks @zmughal

I don't have a problem with the Data::Printer output, I was mostly referring to the mix of it with the tracing of the curl output which is not adding up to a nice output.

Maybe we should just turn off the tracing? I don't think it should be part of the output (maybe only turn it on by a special debugging param)

Just sent in PR #24 as an attempt at that.
