Setting Expires header on IIS 7

I'm trying to set an Expires header through the IIS 7 UI in Vista. The
documentation talks about the HTTP Response Headers in Features View,
but I see no such feature on any of my sites.

I tried
appcmd list config "cozitest"
where "cozitest" is the name of my website. It fell over on the
"extension" attribute in the entry in my web.config:





type="System.Web.WebPageTraceListener, System.Web, Version=2.0.3600.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>






warningLevel="1"/>
>



Commenting it out made appcmd happy, but it didn't make any difference
to the UI.

I then tried

appcmd set config "cozitest/images" /section:staticContent /
clientCache.cacheControlMode:UseExpires /clientCache.httpExpires:"Fri,
28 Jul 2008 15:30:00 UTC"

but I got

ERROR ( message:Can not set attribute "cacheControlMode" to value
"UseExpires"..
Reason: This configuration section cannot be used at this path. This
happens when the section is locked at a parent level. Locking is
either by default (overrideModeDefault="Deny"), or set explicitly by a
location tag with overrideMode="Deny" or the legacy
allowOverride="false".
.. )

Trying
appcmd list config | grep -i override
yields nothing.

At which point I'm going home for the night.

When you get errors about sections being locked at a parent level, it
means that the sections needs to be "unlocked" to allow delegated
admin access at the child level.

You will need to do one of the three thinsg that the error response
mentions -- either change the default delegated admin from "deny" to
"allow", or explicitly use a location tag to allow override or change
the override mode to "allow". Or make the modifications in
applicationHost.config in non-delegated-admin fashion (i.e. like how
one changes config in metabase).

It's a bit tricky, but this is left-over from ASP.Net's concepts that
have to be carried forward for compatibility.

Once you do that configuration, your command should work. I tried it
out myself.

Thanks, David.

I changed system.webServer/staticContent/overrideModeDefault to
"Allow" in config\applicationHost.config and then did an iisreset, but
it makes no difference. The "appcmd set config ..." fails with the
same error.

I think I need slightly more explicit directions. I was in your league
when it came to IIS 6 and below, but I'm an IIS 7 neophyte

Regardless of this, shouldn't I have "HTTP Response Headers" as a
feature in the IIS Manager?

You can open %windir%\system32\inetsrv\config\applicationHost.config ,
find the section definition for "staticContent" near the top of it,
and it'll have an "Deny" in it. Change it to Allow, and delegated
access should be enabled. At that point, your appcmd command should
work.
