How to override the HTTP Date header?

[David Wang [Msft]]

If your intent is to somehow transfer the file such that the resultant
file's datestamp is the same as the original, I'd like to ask you how the
client that receives the streamed file is going to do that.

Hi,

I'm trying to override the HTTP Date header the IIS (in
this case IIS4) outputs. If I do a Response.Clear, it
clears everything except the following:

HTTP/1.1 200 OK
Server: Microsoft-IIS/4.0
Date: Fri, 11 Jul 2003 01:05:57 GMT

I want to replace the Date header (duplicating seems to get
the second date ignored). The reason being that I'm
streaming a file from an ASP page and the Date field is
always populated with the current date/time, rather than
the date/time of the file I'm streaming.

I'm populating the content-disposition header, but the
dates in that seem to be ignored completely.

Any ideas?

Soon'ish

The Date header is ignored completely, it's there only to state the server's
current time. You should be setting Modified header to reflect the content's
last modification time.

I have a custom web application that required that Server Date/Time be manipulated. Never did find a way to override the Date header that the server sent, but it is possible to slip in an additional date header before the one the server inserts. It's not clean, must be done for each page and relies on whatever is on the other end respecting the first Date header, but it does work - at least it solved my problem.

<%

Response.Status= "200 OK" & vbCrLf & "Date: " & [Your Custom Time/Date Here]

%>

Headers received by client will resemble this:
HTTP/1.1 200 OK
Date: Mon, 28 Feb 2011 19:20:59 GMT
Server: Microsoft-IIS/5.0
Date: Fri, 04 Mar 2011 16:20:59 GMT
