Sun Java System Web Server 6.1 SP9 Performance Tuning, Sizing, and Scaling Guide


The parameter find-pathinfo-forward for the PathCheck function find-pathinfo and the NameTrans functions pfx2dir and assign-name can help you improve your performance. The find-pathinfo-forward parameter instructs the server to search forward for PATH_INFO in the path after ntrans-base, instead of backward from the end of path in the server function find-pathinfo.

Note –

The server ignores the find-pathinfo-forward parameter if the ntrans-base parameter is not set in rq-\>vars when the server function find-pathinfo is called. By default, ntrans-base is set.


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="" 

This feature can improve performance for certain URLs by doing fewer stats in the server function find-pathinfo. On Windows, you can also use this feature to prevent the server from changing "\" to "/" when using the PathCheck server function find-pathinfo.
