Sun Java System Web Server 6.1 SP10 Administrator's Configuration File Reference

pfx2dir

Applicable in NameTrans-class directives.

The pfx2dir function replaces a directory prefix in the requested URL with a real directory name. It also optionally allows you to specify the name of an object that matches the current request. (See the discussion of assign-name for details of using named objects.)

Parameters

The following table describes parameters for the pfx2dir function.

Table 4–14 pfx2dir Parameters

Parameter  

Description  

from

URI prefix to convert. It should not have a trailing slash (/). 

dir

Local file system directory path that the prefix is converted to. It should not have a trailing slash (/). 

name

(Optional) Specifies an additional named object in obj.conf whose directives will be applied to this request.

find-pathinfo-forward

(Optional) Makes the server look for the PATHINFO forward in the path right after the ntrans-base instead of backward from the end of path as the server function find-pathinfo does by default.

The value you assign to this parameter is ignored. If you do not wish to use this parameter, leave it out. 

The find-pathinfo-forward parameter is ignored 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.

This feature can improve performance for certain URLs by reducing the number of stats performed in the server function find-pathinfo.

On Windows, this feature can also be used to prevent the PATHINFO from the server URL normalization process (changing '\' to '/') when the PathCheck server function find-pathinfo is used. Some double-byte characters have hexadecimal values that may be parsed as URL separator characters such as \ or ~. Using the find-pathinfo-forward parameter can sometimes prevent incorrect parsing of URLs containing double-byte characters.

bucket

(Optional) Common to all obj.conf functions.

Examples

In the first example, the URL http://server-name/cgi-bin/resource (such as http://x.y.z/cgi-bin/test.cgi) is translated to the physical path name /httpd/cgi-local/resource (such as /httpd/cgi-local/test.cgi), and the server also starts processing the directives in the object named cgi.


NameTrans fn=pfx2dir from=/cgi-bin dir=/httpd/cgi-local name=cgi

In the second example, the URL http://server-name/icons/resource (such as http://x.y.z/icons/happy/smiley.gif) is translated to the physical path name /users/nikki/images/resource (such as /users/nikki/images/smiley.gif). 


NameTrans fn=pfx2dir from=/icons/happy dir=/users/nikki/images

The third example shows the use of the find-pathinfo-forward parameter. The URL http://server-name/cgi-bin/resource is translated to the physical path name /export/home/cgi-bin/resource.

NameTrans fn="pfx2dir" find-pathinfo-forward="" from="/cgi-bin"
dir="/export/home/cgi-bin" name="cgi"
