The HTTP headers returned from the above URL look something like:
HTTP/1.1 200 OK
Set-Cookie: N_T=; path=/; domain=adwords.google.com;expires=Thursday,
01-Jan-1970 00:00:00 GMT
Set-Cookie: N_T=; path=/; expires=Thursday, 01-Jan-1970 00:00:00 GMT

Mathopd (<http://www.mathopd.org/>) is "a very small, yet very fast
HTTP server for UN*X systems".
Further on in the HTML we see """<META name="type"
content="topic.cs">""". The topic.cs portion of that tag suggests to
me that ClearSilver (<http://www.clearsilver.net/>) is being used for
the templating of the page. A little digging around the ClearSilver
site finds this interesting snippet
(<http://www.clearsilver.net/examples.hdf>): "Here are some examples
of websites and applications built today using ClearSilver. The host
programming language is also listed: ... Google Groups 2 - The new
version of Google Groups uses ClearSilver. (C++/Python)".
None of this directly addresses your question with regards to the
"persistency layer" that they use, but it does provide relatively
strong evidence of the Python-related technologies that they are using
for user-visible portions of their services.
