Has anyone implement a mechanism to retain the cache up to a minimum cache
time even though it is supposed to get invalidated? I asked this because I
don't want to increase the load on the database server for caches that are
frequently invalidated and a database retrieval is required. I want to be
able to keep the cache and use it within a specified small period of time
(the minimum cache time mentioned above).
thanks,

Is there some problem with the simple approach of not invalidating in any
manner other than the desired timeout?

Say the same cache object is dependent on the output of several pages
returned from different web methods. I have a web method (call it WM1) and I
want only this web method to retain the cache even though the cache is
supposed to get invalidated. All the other web methods dependent on this
cache objects will refresh the data from the database after the cache get
invalidated. If I don't invalidate the cache and utilize the timeout then
all web methods other than WM1 will get the data from the cache instead of
from the database. In other words, my goal is that the data returned from
WM1 does not require to be up to date within a small time limit (minimum
cache time) whilst the data returned from other web methods require to be
most up to date.

Hi,
I'm writing an application in which a client (C#/WinForms) and server

with the server but for scalability reasons there is not a one to one map
between a session and a physical TCP connection. A client may disconnect the
TCP connection if it is idle for more than 60 seconds... yet a conceptual
"session" may last for days at a time.

Hi,
I' trying to implement a callback method when a cache object expires
I want to do this to automatically logout user after a timeout (for demo
purposes)
My thought is, when user logon, create a cache object which expires after,
let's say, 15 minutes, and in that moment, to direct user to a page telling
the time to run demo app was expired.

Hi-
I am having a hard time decided where I should be implementing my Cache
code. I store most of the DataSet's that I need in the Cache. I was doing
it in the bind method of my pages, but then I thought it would be cleaner to
maybe at the Cache code directly in the DAL. So, for example I might have a
DAL method to get products that looks like this:
public DataSet GetProducts()

Hi,
I think this question requires an in depth understanding of how a browser
cache works. I hope I can reach an expert here.
I may have found a quirk in the asp.net documentation or I don't understand
what the SetAllowResponseInBrowserHistory does.
While researching caching I tried the code sample at the following page :

Hi All,
what is the diference between these two cache control header.
no-cache and no-store.
I have read the w3.org explanation.
So lets say I am using only no-cache ....my understanding is that
nothing is cached and nothing is writen to disk.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
