How to prevent org-mode from exporting external links

Question

In my org document, I have some urls that I would like to see exported plain-text, not as links. For example, if I have this in my org document,

http://www.pharo.org

exporting to HTML will result in this

<a href="http://www.pharo.org/">http://www.pharo.org/</a>

but I would like

http://www.pharo.org

Org automatically recognizes external links even without using the link syntax:

Org also finds external links in the normal text and activates them as links.

Answer 1

Place the hyperlink in = tags to denote org-code verbatim.

Org-mode text like this:

=http://www.pharo.org=

will get exported to HTML that looks like this:

<p>
<code>http://www.pharo.org</code> 
</p>

Answer 2

According to ORG Manual (12.9.5 Quoting HTML tags):

@@html:<span>@@your text@@html:</span>@@

is exported as:

your text

In the case of this question:

@@html:<span>@@http://www.pharo.org@@html:</span>@@

is exported as:

http://www.pharo.org

Instead of <span> and </span>, you can use <b> and </b> (ie bold) etc.
