1 ## Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.
3 This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.
9 , c = caseless(headers)
11 c.set('a-Header', 'asdf')
12 c.get('a-header') === 'asdf'
17 Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.
20 c.has('a-header') === 'a-Header'
23 ## set(key, value[, clobber=true])
25 Set is fairly straight forward except that if the header exists and clobber is disabled it will add `','+value` to the existing header.
28 c.set('a-Header', 'fdas')
29 c.set('a-HEADER', 'more', false)
30 c.get('a-header') === 'fdsa,more'
35 Swaps the casing of a header with the new one that is passed in.
39 , c = caseless(headers)
41 c.set('a-Header', 'fdas')
43 c.has('a-header') === 'a-HEADER'
44 headers === {'a-HEADER': 'fdas'}
