Something I bumped into today: The first time Internet Explorer loads a URL, it sends an “HTTP_Accept” request header with the list of MIME types it accepts, like so:
HTTP_ACCEPT = application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
Any subsequent request of the same URL, though, only sends “*/*”:
HTTP_ACCEPT = */*
Of course I watched this through an ASP page which wrote out Request.ServerVariables("HTTP_Accept")
. I wasn’t sure if it was IIS or IE‘s fault tho, so I checked the raw headers with Fiddler, and it’s definitely IE.
What’s especially strange is that I can find little or no mention of the problem. Anyone else heard of (or conquered) this?
It rather messes up a page I’m working on…
UPDATE: See here for a bug and workaround demo article I just put together.
I have found the same problem and only have found notes that <a title="" href="" ><acronym title="Internet Explorer">IE</acronym></a> mishandles HTTP_ACCEPT, but no info on why or how to fix it.
<br>Did you find anything further since this post. If so, I’d appreciate relaying anything useful. Email below.
<br>Thanks,

Thanks Shekster,
<br> Unfortunately, it sounds like you’ve seen more than I have. I’d be interested in seeing those notes, and in anything else you find.

Unfortunately, this is a limitation in Internet Explorer 5/6/7.
I’d be interested to hear about the problems you’re encountering due to this limitation.
