In a blog post I use the following PHP to set the content-type of a response:
header('content-type: application/json; charset=utf-8');I just got a comment on that post saying that content-type needs to be capitalized, Content-type. Is this correct? It seems to work for me with all lower-case, and I assumed the HTTP headers were case-insensitive. Or does it just work because browsers are nice?
