caching a value for Site

Question

User968218215 posted

Hi,

I want to cache a string value for 15 mins for my website for all users so the site does not hit a function until the 15 mins are up.

If strEuro_Buy = String.Empty Then
            strEuro_Buy = getPrices("EUR.buy")
        End If

I have been looking on google and think that the below is close -

HttpContext.Current.Cache.Insert("CacheKey", strEuro_Buy, Nothing, New TimeSpan(0, 15, 0), Cache.NoSlidingExpiration, CacheItemPriority.High, Nothing)

Am I going in the right direction or should i be looking at sessions?  Im a little confused how this would work for all users to the site.

Thanks for all help...
