v1.8.2

The proxy now safely handles a failing RequestConfigProvider.
This enables applications to use dynamic RequestConfigProviders, e.g. a network bound source like Redis, where errors might occur.

Changelog

76960ac Merge pull request #84 from jensneuse/feature/requestconfigprovider-return-err
321217f add test for a failing request config provider
40d2dae make RequestConfig return value optional (pointer) & add err return value
97d81ff update fasthttpproxy to handle RequestConfigProvider errors
770a80c update proxy http handler to handle RequestConfigProvider errors properly

v1.8.1

With this release proxy tests are now structured in a way to enable easy extensibility of the proxy.
