Unfortunately, a lot of sites, especially those of major companies, tend to have constantly changing URLs, which presents a problem with OW. On these sites, it's not unusual to see both the 3rd-level domain and the file path change.

I even seem to remember this creating the effect on one or two sites of having multiple username/password combinations stored in the keychain by OW, with the end-effect being that multiple loads of the same page end up with a different login pre-filled each time depending on which server happens to handle your request.
