I'm trying to login to a site using python-requests, but cannot seem to login using the code below:

```
import requests

session = requests.Session()
data = {'j_username': 'name@gmail.com'}
session.post('http://www.broadinstitute.org/gsea/login.jsp', data=data)
r = session.get('http://www.broadinstitute.org/gsea/msigdb/genesets.jsp?
collection=CP:BIOCARTA')
print(r.content)

```

I don't believe I am doing anything wrong here, though, as I followed some posts online.
