How to access Google Cache?

[Vacilando]

Hi,

In an application I build I sometimes need to check on a page, but it
is enough for me (and presumably much faster) if I could read its
latest copy from Google Cache.

Is there a way to fetcha page from Google Cache programmatically?

Thanks!

And what about memcache ?

It's not very clear (at least to me) what you're trying to do. If you
have objects that are being pulled from the datastore, then you should
definitely use the memcache API as previously mentioned where
appropriate. However, if you're trying to get a link to a Google
Cached Page, the Search AJAX API exposes a cacheUrl property that you
can use in the JSON response.

Thanks.

My intention is to be able to use an intelligent agent to examine
other websites' pages - and then flagging pages that contain something
important (words, patterns, etc.)

I think the question is whether or not there's a convenient way to
retrieve the url from google's cache, instead of pushing the request
out onto the (potentially slow) internet.

There certainly is such a way. Use the urlfetch API and make the
request against the google cache. For instance, urlfetch.fetch('http://
www.google.com/search?q=cache:en.wikipedia.org/wiki/Namibia'). All the
expected limitations apply though, in that this will only work for
pages not restricted by robots.txt, and you don't have control over
which time version of the page is returned.
