Map a URL to a local file in Windows

Question

Is there a way to map a URL to a local file so that when IE sends a request for that URL it gets the content from a local file?

For example: http://www.example.com/file.zip ---> C:\file.zip

I'm trying to achieve a permanent "cache" for some specific files so that IE always retrieve those files from the harddrive. And then I need a way to change the content of those files if needed.

Something like a permanent entry in the IE cache that never expires and is never deleted.

EDIT:
Could this be done with a proxy autoconfiguration file? (those with .pac extension)

Answer 1

I found a couple of tools that do exactly this.

• Fiddler
  Check out video #2 in this page for the AutoResponder function.

• Charles Proxy
  Read about its Map Local Tool here.

Answer 2

Im not sure why you'd need this. It would worry me for security issues (does he really need to redirect www.mybank.com like that?) But lets assume you have a good reason.

You ask for a hard task; how is the cache to be updated, if it never hits origin servers? What is the criterion for a cache reload? "Never change, unless I want it to change for some reason"

I think the closest you can get is a caching proxy. Id check the docs on squid to see if you can lock certain content in. This won't work (by design) for https sites though.
