.net - Force IE to get a page -

-

i've tried numerous ways ie8 reload page failed. ie keeps using it's internal cache without asking webserver it.

i'm sending following headers webserver:

response.add(new stringheader("expires", datetime.utcnow.addyears(-1).tostring("r"))); response.add(new stringheader("cache-control", "no-store, no-cache, must-revalidate, max-age=0")); response.add(new stringheader("pragma", "no-cache")); response.add(new stringheader("last-modified", datetime.utcnow.tostring("r")));

it's 1 of many combinations i've tried.

how make ie fetch page every time (without forcing users turn off caching inside ie)?

the proper way send these http headers in response:

pragma: no-cache expires: -1 cache-control: no-cache, no-store

using them makes work in ie without other modifications.
