Hi Mike & WALDO,
After some further discussion with some other engineers, they said that the
one 1 day fixed expire value is not the exact behavior and the actual code
logic is a bit different from that. For the problem you encounter, it might
be a specific issue. Due to the support limitation in newsgroup, it is a
bit hard for me to further involve them. If this is an important issue, I
would suggest you consider contacting CSS for further troubleshooting:

Thanks for your inputs.
I've also forwarded this question to some other ASPNET dev engineers. I'll
post here is if there is any further information about this issue.

I am having the exact same problem. I am using VS2008 (.Net 3.5) and I
can't set the Expires date out any further than one day.
Doing a little reflection, I see that in the HttpCachePolicy class,
SetExpires() method, if the expires is already set, it will only change
if the new expiration date is less than the existing one.
I have removed all of my custom HttpModules and discovered that none of
mine are setting the expiration.
Somwhere in the pipeline, something built in is pre-setting the
expiration date to one day forward from the request.
I experience the same effect whether I use Response.Cache.SetExpires(),
Response.Expires, or Response.ExpiresAbsolute.
Sometimes the greatest solutions come from the simplest logic.
Being told "No" is merely the incentive to do it anyway.
