added WinBox support in webproxy-test package

hello guys mikrotikls added WinBox support in webproxy-test package
but do they show us the meaning of the settings inside it.And if u can go to
http://forum.mikrotik.com/t/what-is-the-differnce-between-ip-proxy-and-web-proxy/6015/1 and follow the conversation between me and sergejs u will see that we have two things according to sergejs’s opinion:

  1. Using web-proxy test package, there will be only proxy in ‘ip proxy’, MikroTik proxy that provides caching facility.

  2. Using regular ‘web-proxy’ package, you will have,
    ‘ip proxy’, something like HTTP and FTP firewall or to redirect requests to external proxy.
    ‘ip web-proxy’, proxy with caching.
    No, you have to use one, ‘ip proxy’ or ‘ip web-proxy’.

But b4 version 2.9.19 i looked to what sergejs says then i found that when
i have:
1-webproxy-test package i will only have ip proxy
2-web-proxy package i will have ip webproxy with caching

but now the mikroik guys add the new feature which is related to 1 and has a caching feature.What is going on?
i need an explanation?
thanks.
