Case sensitivity of host names #116

Closed Gitoffthelawn closed 4 years ago

Gitoffthelawn commented 4 years ago

The RC manual states that host names are currently case sensitive.

If I'm reading RFC4343 (not a fun read) correctly, hosts resolved by DNS are not case sensitive.

Thus, could sites bypass Request Control if they just used mixed-case host names?

If so, can this be fixed?

I too was wondering about the same when reading the manual yesterday and then came across this workaround. Not sure if anything has changed since then.

The match pattern that is constructed matches case sensitively. I think Firefox resolves host names in lower case.
