hello,

I have this block of code in my page:

<a id="home" href="<txp:site_url />" title="back to homepage">
<span class="arr"></span>
home</a>

<a id="projects" href="<txp:site_url />projects?c=illustration&p=1" title="">projects
<span class="arr"></span>
<img src="" />
</a>

<a id="about"<txp:if_section name="projects">class="low"</txp:if_section> href="<txp:site_url />about" title="">about
<span class="arr"></span>
<img src="" />
</a>

<a id="contact"<txp:if_section name="projects">class="low"</txp:if_section> href="<txp:site_url />contact" title="">contact
<span class="arr"></span>
<img src="" />
</a>

which is apparently requesting the page address each time a site_url tag is called.
is that normal..?

thank you
