How To: Disable Automatic Proxy Caching In Internet Explorer
The Automatic Proxy Result Cache is a performance enhancement that was added to Internet Explorer 5.5 and later. The purpose of the cache is to reduce the client-side processing of the automatic proxy configuration script. When Internet Explorer is configured for the usage of automatic proxy configuration, it caches the information which is already returned. In case a proxy server fails, you might then get an error message, although programs are available. By a simple setting, you are able to disable caching in order to ensure that the browser checks for the latest information at any time.
