I build a system where a Windows service iterates through a file and
sends each line in the file as a record to a database, by calling a web
service asynchronously. It runs on a w2k server.
What I notice is:
When the web service gets called, there seems to be a slowness and
potential for missed calls - my guess is because it's being moved into
memory. This causes problems as records are dropped. My solution is
to redo the load if it notices that records are missing.
One thought I had : Is it possible to force the web service to stay in
memory ( pre-cached, basically ) so that it's /always/ ready to serve?

Yes, It's possible but you must use ISA Server in cache mode or in
integrated mode.

Yes, It's possible but you must use ISA Server in cache mode or in

Can I just do this:
[WebMethod]
(
Description="my method",
CacheDuration=4 3200)
]
And set it to some incredibly high value ( like 48 hours ) ?

Where? In IE or where do you 'll want to set cache duration?

Actually that's not what I want.
That will cache results that are to be reused.
I just want the whole service to reside in memory for fast access.
Do I have to buy a whole nother product just to do that?
Can't I just change a setting in IIS 5.0 ?

Hi,
I just thought I'll give my idea on this. Usually IIS is very efficient
in handling multiple requests. In your case the only problem might be IIS
throwing exception saying multiple users are connected(more than the expected
lmit). One way to handle this is, always keep the number of request to a lmit
say 20. For e-g start hitting asmx with 20 requests asychronously once the
call back gets a response span another request there by u maitain the number
of hits to your asmx.
Hope this give an idea.
Thanks,
Ravi

One approach uses the old familiar Session object which I've used in the
