Firstly, "redirect" has a meaning in HTTP and it has nothing to do with 
what you seem to be wanting to do.

You are using cache_peer, which is the directive you need to be looking 
at for the "HTTP routing" that meets your need.

However, there are some things that look odd in the details you 
provided. I suspect they are related to other things not mentioned that 
you have dome to the system setup thinking "redirect" was needed.

This is a reverse-proxy. The CONNECT method is not meant to be sent to 
reverse-proxies.

"default" indicates the peer is able to handle any traffic and can be 
used as a backup route when DIRECT fails.

You should not use that option on a peer where only certain site/domain 
are serviced.

What does your logformat define all those log fields to mean ?
   There are 4 IP addresses involved in a proxy transaction and it is 
unclear why the xx.xx.xx.xx is the one being logged.


Why are you using port 8080?
   Last I saw Microsoft do not host their website using port 8080.

Hint: for "just an example name" use the domains which are registered 
specially for that purpose: example.com, example.net, example.org. It 
avoids confusing us into thinking microsoft.com is *actually* the domain 
you are hosting - there are implications to hosting their site which 
change the answers you could get.
