Map couch paths to static html files. Couch paths are accessed through rewrites. Html files are mapped however.

Loop through a view and put request content in a file
for row in db.view('ddoc/view'):
  slug = row.value['slug']
  r = requests.get(_url(slug))
  with file('%s/%s.html'%(static_dir,slug),'w') as f:
    f.write(r.content) # r.content.encode('utf-8')
