    GetHttpRequestData missing "If-Modified-Since" and "If-None-Match"


      I'm using CF8 on IIS6/Win2003 Server.


      In my cfm I have:

      <cfset reqheaders=GetHttpRequestData().headers>
      <cfdump var="#reqheaders#">

      ...which gives:

      CookieCFID=[removed]; CFTOKEN=[removed]
      Host[my test server]
      User-AgentMozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20090824 Firefox/3.5.3


      But if I look at the actual headers being sent from my browser (using Firefox LiveHTTP add-on), it shows I am sending "If-Modified-Since" and "If-None-Match" headers.


      GET /path/to/cfmfile.cfm HTTP/1.1
      Host: [removed]
      User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/2009011913 Firefox/3.0.6

      Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7

      Connection: keep-alive
      Cookie: CFID=[removed]; CFTOKEN=[removed];

      If-None-Match: ""0134E50193C69AD753656B0513FCB28C""
      Cache-Control: max-age=0


      Is there some reason IIS would "steal" those headers before handing over control to ColdFusion?  Or does GetHttpRequestData sometimes "miss" headers?  Other ideas?  Is there any other way I can get at the raw HTTP request from within ColdFusion?


      I'm at a loss.  Others have used the same process and no one seems to have this issue.

      (see: http://www.petefreitag.com/item/235.cfm or http://admin.mxblogspace.journurl.com/?mode=article&entry=1853 for examples)


      I've tried accessing the page using Internet Explorer instead.  It also is not showing those headers, but I have not sniffed IE's actual headers being sent so I can't be sure those headers are included (but I think they are, since IE implements conditional GET).
