Overview

Current request context data.

`kong.ctx.shared`: A table that has the lifetime of the current request and is shared between all plugins. It can be used to share data between several plugins in a given request.

Values inserted in this table by a plugin will be visible by all other plugins. One must use caution when interacting with its values, as a naming conflict could result in the overwrite of data.

Usage: // Two plugins A and B, if plugin A has a higher priority than B's // (it executes before B), and plugin A is a Go plugin:

// plugin A PluginA.go

func (conf Config) Access(kong *pdk.PDK) {
	err := kong.Ctx.SetShared("hello world")
	if err != nil {
		kong.Log.Err(err)
		return
	}
}

// plugin B handler.lua function plugin_b_handler:access(conf)

kong.log(kong.ctx.shared.foo) // "hello world"

end
