Memcache problem with Python feedparser !!

[Ayan]

Dear Friends,

I am using Python Feedparser (http://code.google.com/p/feedparser/) to
read some RSS feed for my application.

I want to Cache the RSS feed for 1 hour. No need to do the UrlFetch
every single time.

For that, I wrote this CODE -
--------------------------------------------------------
def get_data(NewsID):
data=memcache.get(NewsID)
if not data:
data=feedparser.parse('http://mysite.com/feeds/'+NewsID+'/')
if not data:
memcache.add(NewsID, data, 3600)
return data
--------------------------------------------------------
The format of NewID is: ABC1234567890 string format

PROBLEM: It seems, it is not Caching at all !!

Can you please tell me whats wrong ???

Probably your instance doesn't live long enough, or your RSS is too big, or
you aren't escaping the XML for the data type you are using.

Oh, and memcache, never going to live for a full hour. Not what it is for.
I give it 25 minutes tops.

I don't know Python, but isn't your second "if not data" basically saying that if you don't have data, then put it in Memcache - seems to be the wrong way round to me!
