title: Excessive recrawl of ColdFusion dynamic pages
body: <p>The folks who use ColdFusion and serversideincludes are having issues with excessive recrawls on dynamic pages because there is no datelastmodfied set, which causes excessive server traffic. You can laugh if you want, but when I tell them the solution is setting a last modified date on the pages I get a universal huh? how do you do that? I opened a case with google originally and was told that yep, it's a page date problem. I have done a lot of research to try and find how to code this in the header and most of what I found talked about pulling a date from a page.
  I did determine that it probably could be done using the <code>CFHEADER</code> tag. I'm just not sure about implementing. 
  Can I tell them that adding something like </p>
  
  <pre><code>&lt;cfheader NAME="datelastmodified="Mon, 01 Feb 2013 08:00:00 GMT"&gt;
  </code></pre>
  
  <p>will suffice? Not sure about the date format, if the day name is required.
  Have I tried just asking one of the webmasters to try this? No I haven't. I would like to know that I am at least on the right track before taking up too much of their time. And so far none of them have come up with a solution on their own other than useing robots.txt to block the crawl or things along those lines.
  Any suggestions or thoughts would be appreciated.</p>
