You can add a random number after the url. For instance,
url=http://yourapp.appspot.com/yourpath
url=url+'?'+ random.random()
Good luck.
go2.appspot.com

My app needs to get a fresh copy of a dynamic webpage page every few
minutes. I am fetching date from a URL with this function:
def getUrlData(url):
result = urlfetch.fetch(url, headers = {'Cache-Control' : 'no-
cache', 'Pragma' : 'no-cache'})
if(result.status_code != 200):
logging.error( "Error getting URL data: %d" %
result.status_code)
return None
logging.warn("Fetch %s response headers: %s" % (url, repr
(result.headers)))
return result.content
However, it seems like I am still getting cached data. The logging
statement output the following:
Fetch [URL] response headers: {'Content-Length': '21883', 'X-Google-
Cache-Control': 'remote-cache-hit', 'Age': ' 633', 'Expires': 'Mon,
02 Mar 2009 23:49:23 GMT', 'Vary': 'Accept-Encoding', 'Server':
'Apache', 'last-modified': 'Mon, 02 Mar 2009 23:34:23 GMT',
'Connection': 'close', 'Via': 'HTTP/1.1 GWA (remote cache hit)',
'Cache-control': 'public; max-age=600', 'Date': 'Mon, 02 Mar 2009
23:34:23 GMT', 'Content-Type': 'text/html; charset=ISO-8859-1'}
Does anyone know how to ensure a fresh page?
