Why the server try to compile a comment?

[Andrés Ferrer]

I´m newbie in django and I worked a entire sunday in the first app tutorial. all good until a try to use namespace for the url at the end of part 3 and I try to keep all examples in my code, then I commented the old line of code, but de browser still traying to compile the old line and give me a NoReverseMatch at /polls/ for 'detail'.

Solution: When I deleted de old line, the render is sussesfull and the new line of code with the correct namespace is rendered.

My question is the summary subject. Maybe is an incorrect question, maybe isn´t the server and it´s the browser, I don´t know, but is curius, isn´t it?
