Best way to Invalidate Cache.

Invalidate Cache:

------------------------

I have a Scenario that when user went login i need to cache data based on dropdown (pre,post,all)

Key =pre,

Key =post,

key =all,

some time user may or may not go through all 3 options but when user creating new order that time i need to invalidate all 3 cache beacause i don't no which time the order will list(pre (or) post (or) all) as now it working but suggest me the good way to handle this scenario.

There is an InvalidateCache policy.

If you have three items to cache, I suppose you can use three distinct cache keys.

If you want to invalidate those cache items, call the InvalidateCache policy with those three distinct keys. eg

<InvalidateCache name="CacheInvalidate-1">
    <CacheKey>
        <Prefix>statedata-pre</Prefix>
        <KeyFragment ref="username"/>
    </CacheKey>
     ...

And

<InvalidateCache name="CacheInvalidate-2">
    <CacheKey>
        <Prefix>statedata-post</Prefix>
        <KeyFragment ref="username"/>
    </CacheKey>
     ...

Etc.

Am I answering the question?
