Hey,
It depends on the configuration and exactly how the domains will be "redirected".
The browser compares the address in the address bar with that on the SSL certificate. In other words, if you use a DNS alias to have domain.net resolve to domain.com, your SSL certificate will be marked as invalid. The browser has no part to play in DNS resolution and will have no idea the certificate should be accepted; it will trigger a warning because domain.net is not listed on the certificate.
However, if you used an HTTP redirect from http://domain.net to https://domain.com, this would work; the browser is being told to initiate a new connection direct to domain.com and as such, the address in the address bar will change. Note that for redirecting from the secure (https://domain.net) will not work as the certificate will be rejected.
If you are using a DNS alias or redirecting from https://domain.net to https://domain.com, you need a SAN certificate with the names of all the possible domains listed. This will be trusted by the browser and you will not receive any warnings on the domain URL side of things.
