set Expires tag for images?

[Paul W]

Hi - I want to reduce the download time of various pages by setting the
'Expires' tag for various images to a future date (this will then stop the
browser from re-requesting these for each new session).

I'm hosting on a commercial service so I don't have direct access to IIS
configuration. Is there anyway I can control this from my server-side code?

Thanks,

Paul.

Not if the images are served directly by IIS. Your ISP should be able
to change the server configuration to allow for caching.

BTW, you should prefer Cache-Control: max-age over Expires.

Currently the images ARE directly served by IIS. Can you point me to how
else I could do this so I can set the "Cache-Control: max-age"? Thanks,

Paul.

You could implemment a HttpHandler that serves your images, but this is
really a waste of time. Ask your service provider to change your IIS
configuration.
