This is an odd one. I have a page with some dynamic content on it - loaded server-side from an XML file. When I first visit the page, it works fine, but if I follow a link to the same page from inside the site, it sometimes renders correctly, and sometimes not. Pressing 'Refresh' always fixes it. The easiest way to replicate the problem is to browse to http://temp.healdlaw.com/default.aspx and then press the 'Home' link at the top a few times. I doesn't happen evey time, but around half the time it messes up the rendering of the three panels towards the bottom of the page. If I save the 'broken' HTML source and refresh, then the page renders correctly, and comparing this correctly-rendered HTML source with the one that DIDN'T work reveals that they are identical. Since the order of the panels is random, and therefore changes occasionally, I am wondering if it is a caching issue, or if perhaps there is something in the HTTP header that is confusing things? I'd be interested to hear any advice you have to give me! == URL of affected sites == http://temp.healdlaw.com/default.aspx
