Are http headers case sensitive?

I know the content-matching will be case sensitive, but when doing a header lookup, is the header name itself case sensitive? Meaning, will this: [HTTP::header "clientid"] ...

It's case insensitive. Here's a quick test: 

 
 when HTTP_REQUEST { 
     Insert a test header with a name of TEST and a value of "some_value" 
    HTTP::header insert TEST "some_value" 
  
     Log the value of the header with variations on the case 
    if {[HTTP::header exists test]}{ log local0. "test: [HTTP::header value test]"} 
    if {[HTTP::header exists TEST]}{ log local0. "TEST: [HTTP::header value TEST]"} 
    if {[HTTP::header exists TeSt]}{ log local0. "TeSt: [HTTP::header value TeSt]"} 
 }

Here is the log output:

: test: some_value

: TEST: some_value

: TeSt: some_value
