Usingnd-pathinfo-for ward
Thefind-pathinfo-forward parameter used in obj.conf can help improve your
performance.It is used with the PathCheck function find-pathinfo and the NameTrans
functionspfx2dir and assign-name. The find-pathinfo-forward parameter instructs the
serverto search forward for PATH_INFO in the path after ntrans-base, instead of backward
fromthe end of the path in the server function find-pathinfo.
Note– The server ignores the find-pathinfo-forward parameter if the ntrans-base parameter
isnot set in rq->vars when the server function find-pathinfo is called. By default,
ntrans-baseis set.
Example
NameTrans fn="pfx2dir"find-pathinfo-forward="" from="/cgi-bin"
dir="/export/home/cgi-bin"name="cgi"
NameTrans fn="assign-name"from="/perf"
find-pathinfo-forward="" name="perf"
Thisfeature can improve performance for certain URLs by doing fewer stats in the server
functionfind-pathinfo. On Windows, you can also use this feature to prevent the server from
changing"\\"to "/"when using the PathCheck server function find-pathinfo.
Formore information about obj.conf, see the Sun Java System Web Server 7.0 Update 1
Administrator’sConguration FileReference.
Usingnostat
Youcan specify the parameter nostat in the obj.conf NameTrans function assign-name to
preventthe server from doing a stat on a specied URL whenever possible. Use the following
syntax:
nostat=virtual-path
Example
<Object name=default>
NameTrans fn="assign-name"from="/nsfc"nostat="/nsfc"name="nsfc"
</Object>
<Object name=nsfc>
Service fn=service-nsfc-dump
</Object>
