kernel-mode cache

Hello,
I enabled odbc logging to a database on a web site on iis6.
I now read that this disables kernel-mode caching. I take it this means for
all web sites on the machine?
How can this be re-enabled?
Thanks SOC.

I suggest you do not use ODBC logging. Use centralized binary logging
or normal text-based logging and periodically process them into a
database if you want. This gives you the benefits of kernel-response
caching, reliability of local logging, and SQL-based access of
periodic refresh of the logs.

Thanks, I'll most likely do that.

IIS6 kernel-mode cache enabled in machine.cfg by adding =
enableKernelOutputCache=3D"true" to

element.

Re: kernel-mode cache

That setting does not do what you think. It only affects ASP.Net's
usage of the kernel response cache. It has no control over the actual
availability of the kernel response cache.

In other words, the kernel response cache is a feature of HTTP.SYS,
exposed by IIS6, and leveraged by ASP.Net through the ISAPI interface
of IIS. HTTP.SYS has its registry key to control kernel response
cache, and IIS has similar configuration. Plus, there are a couple
dozen behaviors required for kernel-response cache.

So, the real answer is that no single setting does what you think. The
real behavior is a combination of dozens of different parameters
control the overall functionality of kernel response cache.

Re: kernel-mode cache

Thanks David.

Does reverting to file logging undo any change that may have occurred?

Thanks Soc.
