IIS/ASP Caching

We are running Windows 2003, IIS 6 and ASP 2.0.50727. I am not very familiar with IIS/ASP caching. We have an application that makes the same requests over and over. (static content as well as dynamic asp requests) From what I have seen the only way to use caching with ASP is to do it at the code level. Is this true? I am not a developer but work on the systems side.

Do you recommend setting Expire HTTP Headers at the IIS level? If I set it to 1 day will this only cache static content for 1 day or also dynamic asp data? I know this caches it at the clients browser. Is there a way to cache these images on the IIS server side? It stores the files in memory?

Thanks

Expires controls caching on the users end, not the server side. Rick has a good start for controlling it. - Doozer Blake
Take a look at this answer, this is, IMO, the best way to do caching on IIS, specially for images, js files, css files, etc: stackoverflow.com/questions/7541032/… - Icarus
Thanks for the link, unfortunately I am running IIS 6 so I don't have the "Output Caching" option in IIS. I have read about Kernal caching with IIS 6 but not sure if its the same or not. - roacha
Icarus, this setting is in IIS correct? When I right click on my Images folder I don't see Output caching as an option anywhere. Its not under properties and it doesn't have the new panel with all the options that include Output caching. Can you give me more details on where exactly I would see this option in IIS 6? Based on a few links I found this feature was started with IIS7. - roacha

You can control overall caching in the web.config:
