I had a conversation with a friend today.
I'm working on a project where I have an XML file that stores the site
structure and some page-centric variables. I have a handful of controls that
will be reading from this XML file.
My initial reaction was to load the XML file once, and then set it to a
cache object, so that it's cached and only updated if the file is updated on
the server.
He said that was unecessary, as IIS/.net will cache frequently accessed
files automatically for you.
Any thoughts on that?

You had the right idea in the first place. Your friend is mixing up caching
with caching. ;-)

Hmm...;o)
So, what, exactly, does IIS/.net cache by default vs. what should I
explicitly cache?
-Darrel
Aye...you are right..
The O/S will likely "cahce" files that are being frequently access to savel
save the disk I/O work...but this is really different than the type of
caching we are talking about (I'm not aware of .Net doing any automatic
caching btw). putting it int he Cache object specifically puts in in the
asp.net worker processes memory space...Besides , the O/S definion of what's
"frequent" could be like hundres of times per
second....where as ours could be like a couple times....what good are
friends for when you got newsgroups??

Well, you *could* argue that the compiled pages are "cached"
server-side, since no recompilation is needed to serve them,
but the primary benefit of caching is the substitution of database
retrievals, contents of XML-based data, etc.
Being able to load frequently-used data from memory,
instead of making data calls is the main benefit.

I see...the main benefit is that I'm at the mercy of IIS or the OS itself
deciding what to cache vs. me being able to tell .net explicitely what to
cache.
Thanks!
-Darrel
TO expand upon the question...is there an upper limit of files I shouldn't
cache myself?
For instance, this site will have about 10 XML files and 3 or so XSLT files.
Is there any reason NOT to go ahead and set all of them to cache objects,
since they'll rarely change on the server (maybe once a week or so at most)?
-Darrel
I thought the web.config file was automatically cached so it was only read
once and there was no perofrmance hit when reading one of the values.

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.

I would like to know how you can figure out how much memory a given instance
of a class is using.
For example, if I load a collection class with 10 items it might use 1KB,
and if I load it with 1000 items it might use 100KB.
How do I measure the amount of memory used once the class is loaded?
Thanks!
