Need architectural help to implement caching

[Girish]

i have to implement caching in my application, can any one tell me
about the good techniques to implement caching, or provide some
architectural help , so i can use it to my application.

i want to control caching dynamically according to my configuration.

Thanks,

You figure out your requirements for the cache, check if there are
a quality solution available that meets those requirements, if yes then
you use that, if no you write your own.

Without knowing anything about app, data and requirements nobody here
can come with a specific recommendation.

Actually, I have to implement a content based website.
my requirements are to cache data by parameters(URL), each page can
have different cache time.
and i have to provide a control panel where site administrator can be
able to clear cache for the specific URL, complete page or whole
site.
or they can also able to change the cache time of a particular page.

Well, I can't say that that really helps guide us with respect to
architectural suggestions.

That said, it sounds like the kind of thing that the Windows Server web
proxy ought to already be able to do. I don't have any first-hand
experience, but it seems like you should be able to insert the proxy
between your web server and the outside world, and let it handle the
caching for you.

If you are doing the website in ASP.Net, the Application cache will do a lot of
what you want.
You can add various objects, set caching time, and set dependencies on other
objects.
You clear objects by simply removing them from the cache.

Be aware, though, that caching is an optimization. Although it practice it
usually does what you want, in principle the cache can be reset at any time,
and does not guarantee that it will cache something for the time specified. The
model is that you write your code to see if something is in the cache, and use
it if is, else create it and add it. Also the application cache may or may not
carry across multiple instances of the web app, or application pooling, or what
have you.
