Question

I want to get the HTML code / data of any website by using server-side javascript. How can I achieve this?

PS: I need this because from client-side javascript i can’t do XMLHttpRequest of external domains due to the same origin policy.

Here is a Quick-n-Dirty solution:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

<xp:label id="labelURL">
    <xp:this.value>
        <![CDATA[#{javascript:
            var url:java.net.URL = new java.net.URL("http://google.com");
            url.openConnection();
            var is:java.io.InputStream = url.openStream();
            var c;
            var result = "";
            while( (c = is.read()) != (-1) ){
                result += @Char(c);
            }
            is.close();
            result
        }]]>
    </xp:this.value>
</xp:label>
</xp:view>

A better solution accessing remote urls is to use http://hc.apache.org/httpclient-3.x/
