Sun Java System Portal Server Secure Remote Access 7.2 Administration Guide

Sample for JavaScript DJS Variables

ProcedureTo Use the JavaScript DJS Variables Sample

  1. This sample can be accessed from:

    portal-server-URL/rewriter/JavaScript/variables/djs/djs.html

  2. Ensure that abc.sesta.com is defined in the Proxies for Domains and Subdomains list in the Gateway service. If this is not defined, a direct connection is assumed, and the Gateway URL is not prefixed.

  3. Add the two rules specified in this sample (if it does not already exist) to the default_gateway_ruleset in the section "Rules for Rewriting JavaScript Source". Edit the default_gateway_ruleset in the Rewriter service under Portal Server Configuration in the Portal Server administration console.

  4. Restart the Gateway:


    ./psadmin start-sra-instance –u amadmin – f  <password file> –N <profile name>– t  <gateway>

<script LANGUAGE="Javascript">

var dJSVar="var dJSimgsrc=\qgateway-URL

var dJSVar="var dJSimgsrc=\qgateway-URL
/portal-server-URL/rewriter/tmp/tmp/jpg\q;"
var dJSVar="var dJSimgsrc=\qgateway-URL
/http://abc.sesta.com/tmp/tmp/jpg\q;"

// All the above statements are rewritten with the Gateway and Portal Server URLs. The required path is prefixed as appropriate. The first rule identifies the right hand side of dJSVar as a dynamic JavaScript variable. This is then passed to the second rule which identifies the right hand side of dJSimgsrc as a JavaScript variable of type URL. This is rewritten accordingly.
