File Cache in Enterprise Server 4.0
Enterprise Server 4.0 uses anew file cache module, NSFC, which caches static
HTML, image, and sound files. In previous versions of Enterprise Server, the file
cache was integrated with the accelerator cache for static pages. Therefore, an
HTTP request was serviced by the accelerator, or passed to the NSAPI engine
for full processing, and requests that could not be accelerated did not have the
benefit of file caching. This prevented many sites with NSAPI plugins,
customized logs, or used server-parsed HTML from taking advantage of the
accelerator.
The NSFC module implements an independent file cache used in the NSAPI
engine to cache static files that could not be accelerated. It is also used by the
accelerator cache, replacing its previously integrated file cache. NSFC has also
been used to cache information that is used to speed up processing of server-
parsed HTML.
File Cache Configuration
The file cache is configured in the
nsfc.conf
configuration file located in the
server_root /https- server-id /config
directory. You can tune the file
cache configuration parameters for improved performance.
