How long is a 302 redirect saved in browser?

Question

Due to a misconfiguration of our webserver the main domain sent a 302 redirect to a new location. We fixed that issue. When emptying the browser cache everything works fine

Answer 1

Using Steve Sounder's Redirect Caching Tests tool (thanks @LeonidVasilev), it seems that the results may not be what are expected. With no expires headers or cookies, the results were as follows:

Chrome 71: Not Cached ✔
Firefox 64: Cached ✕
Safari 12: Cached ✕

So despite what RFC 2616, section 10.3.3 302 Found states, not all browsers follow these guidelines or what might be considered expected behaviour :(
