I want the pattern for removing the &b=128&f=norefer from following url
<p><code>http://www.yahoo.com &amp;b=128&amp;f=norefer</code>   </p>

<p>I want to remove <code>&amp;b=128&amp;f=norefer</code></p>

<pre><code>String finalUrl =decodedUrl.replace("&amp;b=128&amp;f=norefer", "");
                page.setPageUrl(finalUrl); 
</code></pre>

<p>I have used this code but I want code without hardcoded <code>&amp;b=128&amp;f=norefer</code>  in code</p>
