Is there any ill effects of referencing the same js file twice?
<p>I've read the reasons why having someone (say Google) do the hosting of jQuery and other js files is a good thing. However, I have a client that has domains like googlecode.com and googleapis.com blocked (a government agency).</p>

<p>I wanted to keep the Google hosted js files, but also have a local copy on my server for the above client (which is only a fraction of my cliental, but an important one). </p>

<p>Does having the same js file referenced in the same page cause any issues?</p>

<p>This is basically how it looks in my source, 1 listed after the other:</p>

<pre><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"&gt;&lt;/script&gt;
&lt;script src="/js/local/jquery.min.js"&gt;&lt;/script&gt;
</code></pre>
