The days of having your domain hijacked through a proxy in Google are over. This was a huge problem for years and looks like it has been rectified. All of the domains I have that had the 302 hijack issue are all responding correctly.
Google and Microsoft have recently released a new supported tag to allow their spiders to know which “real” version of the page you want indexed, if you have dynamic content.
The syntax is pretty simple: An ugly url such as http://www.example.com/page.html?sid=asdf314159265 can specify in the HEAD part of the document the following:
That tells search engines that the preferred location of this url (the “canonical” location, in search engine speak) is http://example.com/page.html instead of http://www.example.com/page.html?sid=asdf314159265.
This is great news and it should also take care of Proxy Hijacking. Learn More about the Canonical Tag.












The main reason I started the SEO Revolution was out of frustration. Frustration at all of the lies and misconceptions that are posted in forums, given as advice in teleconferences, and even taught in live workshops. "So why didn't all of this work?" " Why wasn't my site successful?" " Why am I still stuck in a rut?" 
Cheers for the very useful infos on Proxy Hijacking.
