Check to make sure that that comparison is valid.  Browsers often cache DNS lookups, images, and 
entire web pages.  Your python runs won't do this unless you've coded that support in.  Also, some 
browsers will start rendering before all of the file is received.  You'll have to do some special 
coding if you want your file to start being written before the full response has been received.
