Sample for JavaScript SYSTEM Variables

ProcedureTo Use the JavaScript System Variables Sample

  1. This sample can be accessed from:

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

  2. Add the rule specified in this sample (if it does not already exist) to the default_gateway_ruleset in the section "Rules for Rewriting JavaScript Source".

  3. 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>

HTML Page Before Rewriting

HTML After Rewriting

<html>

<title>JavaScript SYSTEM Variables Test Page</title>

<SCRIPT>
convertsystem function definition...
</SCRIPT>
<script LANGUAGE="Javascript">
<!--
//SYSTEM Var
alert(psSRAPRewriter_convert_system
(window.location, window.location.pathname,”window.location”));

// Rewriter identifies window.location.pathname as a JavaScript SYSTEM variable. The value of this variable cannot be determined at the server end. So the Rewriter prefixes the variable with the psSRAPRewriter_convert_pathname function. This wrapper function determines the value of the variable at the client end and rewrites as required.
