CB uses SimpleBridge for http layer, you can try to compare cowboy vs yaws bridge and see if they encode data differently, as % char giving me idea to move in that direction

Hi ,

Some update.

I try to switch backend from cowboy to yaws, no issue encountered.

But is this bug with cowboy? i already ask in cowboy irc, they said not related to cowboy.

Hi Dmitry,


I try switch from cowboy using mochiweb on backend, it works.

but other like inets, yaws, webmachine error when start the app. seems i dont have the deps installed for webmachien and yaws, inets.

So this looks like problem with cowboy? not sure about this, related to % as data.

You should uncomment other servers in rebar.config to install and use them
