You could always use ESI for it, but apart from that, there's currently<br>
no way to manipulate the content of a page.<br></blockquote><div><br></div><div>ESI would probably work and be much easier, but reading the wiki (<a href="http://varnish-cache.org/wiki/ESIfeatures">http://varnish-cache.org/wiki/ESIfeatures</a>) it seems like Varnish doesn't yet support the "<span class="Apple-style-span" style="font-family: Verdana, Arial, 'Bitstream Vera Sans', Helvetica, sans-serif; font-size: 13px; ">Content substitution based on variables</span>" functionality. </div>
