btw, did YOU know that cookie names are case sensitive?
@bagder I actually assume that everything is case sensitive … with the exception of mail addresses and domain names.
Filenames are often also not, but its safer to assume they are.
(I once formated a mac in HFS+ extended journaled case sensitve ... for FUN. Yeah, … "fun" I had)
@Ann_Effes @bagder I think the bit before the @ can be case sensitive, but nobody does that in practice.
Probably better to assume everything is unless specified otherwise. Usually because they predates most computers having multiple cases, like domain names.
"I think the bit before the @ can be case sensitive, but nobody does that in practice."
Theoretically yes. In practice I have never encountered any mailserver which implemented it that way. Also to make that work, all parties in a mail exchange would need to support that.
I doubt that this will ever be the case outside artificial "proof of concept" setups.
