RouterOS webproxy issues with Google cached pages

I’m experiencing some weird issue using RouterOS webproxy. Even with no filtering rules, all Google search “cached” results displayed garbled. I mean those webpages shown when pressing “Cached” in Google search results.
Just for info, similar cached pages feature found on other search engines such as Yahoo and Bing work just fine with webproxy enabled.

                 enabled: yes
             src-address: 0.0.0.0
                    port: 8080
            parent-proxy: 0.0.0.0
       parent-proxy-port: 0
     cache-administrator: ""
          max-cache-size: none
           cache-on-disk: no
  max-client-connections: 600
  max-server-connections: 600
          max-fresh-time: 3d
   serialize-connections: no
       always-from-cache: no
          cache-hit-dscp: 4
             cache-drive: system

Any idea folks?

Update: Seems that only happens when using Google Chrome (v8.0.552). Internet Explorer 8 and 9 both display cached pages ok with ROS webproxy enabled.
So what’s going on with the specific browser - webproxy combination? :confused:
