We have upgraded our product from Apache HttpClient to OkHttpClient. But after migration, when special characters like %20(+) is passed in URL param or query param, its been sent to client as is, where it was decoded and sent to client with Apache HttpClient.
eg : http://ip:port/testURL?A%20B -> http://ip:port/testURL?A+B ( Apache HttpClient) http://ip:port/testURL?A%20B -> http://ip:port/testURL?A%20B ( OkHttpClient)
