问题
I'm trying to parse RSS feeds from a url using feedparser in python.
>>> import feedparser
>>> d = feedparser.parse('http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801')
>>> d
{'feed': {'summary': u'<span><h1>Server Error in \'/mobile\' Application.<hr color="silver" size="1" width="100%" /></h1>\n\n

I get nothing in the output, while if you go to the link (http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801) it shows a whole lot of stuff! Maybe it is redirecting me to some other page that does't exist (as I tried crawling individual pages of this website using scrapy, but couldn't, since I was redirected to some non-existant url).
Any help on this would be great. Thanks!

Are you using proxy? If you are, do it this way -
import urllib2, feedparser
proxy = urllib2.ProxyHandler({"http":"proxy:port"})
d = feedparser.parse('http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801', handlers = [proxy])
