[Fixed]-Django – Can I trust receiving the relative URI as exactly the same that is submited by the client?

It would be more flexible if you used request.GET.get() to get the query parameters that you are looking for:

offset = request.GET.get('offset', None)
limit = request.GET.get('limit', None)

or get all the params as a dict:

request.GET.dict()
{'offset':'0', 'limit':'25'}
