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:
| struct | |
|---|---|
| Accept | text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 |
| Accept-Charset | ISO-8859-1,utf-8;q=0.7,*;q=0.7 |
| Accept-Encoding | gzip,deflate |
| Accept-Language | en-us,en;q=0.5 |
| Cache-Control | max-age=0 |
| Connection | keep-alive |
| Cookie | CFID=[removed]; CFTOKEN=[removed] |
| Host | [my test server] |
| Keep-Alive | 300 |
| User-Agent | Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) 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

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.

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).
