Easier Google cache hacking

Jon Rentzsch notes the structure of Google cache URLs:


where xxxxx is a hash to help Google quickly find the cached page, and yyyyy is the URL of the page. He finds that if you change the URL part (yyyyy) it still loads the old page, since it's relying on the hash. He recommends changing the hash so that Google has to look at the url part.

Jon, it's easier than that. Just omit the hash entirely. For example, if you want my blog's cache, go to


It's much simpler.


Avi, you should use the blockquote tag for blockquotes... :-)


Ur technique is excellent...but tell me how do u update the cache content in google

Thanks for this,

I read Jon’s article, but was completely in the dark as to the reason for doing what he does. I simply didn’t get the point of the article. I do now.

You write in your blog, that you explain everything, so let me try and run a little Google something on you, that I have been trying to figure out.

In these two articles, the writers talk about hackers using Google as a proxy to hide behind while executing attacks and assuming there are no graphics to be fetched.

Can you enlighten me in how this works? Is the hacker able to execute an attack while hiding his IP address or is he only able to access privilege information from the Google cache without the information owner knowing about is. What about the graphics, why will graphics make it impossible for a hacker to use Google as a proxy, an can we use this to protect ourselves.



Reaching from cache-store seems undoable when the filetype of the object of your desire is PDF. Google automatically converts into HTML, thus loosing, for instance, pictures. However, judging the performance, Google is converting on-the-fly, thus presumably uses a cache PDF-version (original PDF is long gone). Is there a way/trick/hack of reaching the actual PDF-version from Google's cache?

Interesting, but how do I update google's cache?

A little neat tip: Add a bookmark with "javascript:location.href='http://google.com/search?q=cache:'+document.location.href;"
in the address field, when surfing the net, just select that bookmark to view googles cache of the current page

A bit confused by all of this.. But my question is this: Is it possible then to view a page that has been taken down from the web entirely and another site or rahter "cyber squatter" has picked up on the domain now?

For an example, I have a site I want to view. Google supposedly doesn't find it in their caches but it does find a ton of links to it. Can I view the site through a cached link or a cache of the site even if the site has now been replaced and the new owners of such a domain install a robots.txt file to stop anyone like Webarchive from viewing the site previous history?

do you know if its possible to find the cache of https://something.com?
