A complete noob question, but how exactly do I get values (e.g. path_info) from inside the callback? From the docs, I thought it was a list of tuples, which I thought would make it accessible via lists:keyfind, but I've had no luck. So far, all the examples I've found only show how to print everything with io_lib but not how to access the values by key...

Thanks, --tim

The docs:

Module:Function(SessionID, Env, Input)-> _

Types
    SessionID = term()
    Env = [EnvironmentDirectives] ++ ParsedHeader
    EnvironmentDirectives = {Key, Value}
    Key = query_string | content_length | server_software | gateway_interface | server_protocol | server_port | request_method | remote_addr | script_name. <v>Input = string()
