what is the reason why ie must clear the cache once to have the latest data?
for example, adding, deleting and changing to
< meta http-equiv= "X-UA-Compatible" content= "IE=8,IE=9,IE=10" / >
< meta http-equiv= "Expires" content= "0" >
< meta http-equiv= "Cache-Control" content= "no-cache" >
< meta http-equiv= "Cache-Control" content= "no-store" >
meta tag is also set not to cache correctly.
because that is IE ah, the IE of the http request cache, add a timestamp to the request.
this is the strong (fan) and big (ren) of IE
