Are redirects cached?
In the absense of cache control directives that specify otherwise, a 301 redirect defaults to being cached without any expiry date. That is, it will remain cached for as long as the browser’s cache can accommodate it.
Do browsers cache permanent redirects?
Many people don’t realize that browsers cache 301 redirects. A 301 redirect is a permanent redirect from one URL to another. It only makes sense that a browser should cache a 301 redirect, after all, it is permanent. Your browser is going to send you to the same place it redirected you to last time.
Does not cache 301 redirect?
Don’t try to avoid 301 caching. If you don’t want any user agent to cache your redirect, then simply don’t use a 301 redirect. In other words, 301 caching is here to stay, and semantically, it’s a permanent redirect, so if you’re planning to change the destination URL, 301 is not the right status code to use.
How long does it take for cache to clear?
Depending on how much cache has built up, it can take up to 10-15 minutes.

304 (Not Modified) redirects a page to the locally cached copy (that was stale), and 300 (Multiple Choice) is a manual redirection: the body, presented by the browser as a Web page, lists the possible redirections and the user clicks on one to select it. Not many: the choices are listed in an HTML page in the body.
Is there a way to prevent caching in ASP.NET?
ISP’s, proxies, and other network devices also cache resources and they often use internal rules without looking at the actual resource. There isn’t much you can do about these.
How to prevent the browser from caching a resource?
If desired, those can be added manually in the view. Additionally, JQuery and other client frameworks will attempt to trick the browser into not using it’s cached version of a resource by adding stuff to the url, like a timestamp or GUID.
