I have a problem about useing urllib2 to fetch files.
If I use urllib2 to fetch a file more times in one day, when the files is update, useing urllib2 is still fetch old files.

So how do I force urllib2 to fetch newly files.
Now I have added random no. at the end of URL, but it still fetch old files.

Thanks.

Which URL are you fetching? Could it be possible they are caching this on their side?

someone like this:
which is about Taiwan stock data.(stock no is 8261)

If I fetch more times in one day, it can't to fetch the newly data, even if the stock is close.
I also add random no. at the end of URL, but can not work.

Thanks.
