1. setHeader :: HasHeaders a => CI ByteString -> ByteString -> a -> a

   snap-core	Snap.Internal.Core

   Sets a header key-value-pair in a HasHeaders datatype. If a header with the same name already exists, it is overwritten with the new value. Example:

   ghci> import qualified Snap.Types.Headers as H
   ghci> setHeader "Host" "localhost" H.empty
   H {unH = [("host","localhost")]}
   ghci> setHeader "Host" "127.0.0.1" it
   H {unH = [("host","127.0.0.1")]}
   

2. updateHeaders :: HasHeaders a => (Headers -> Headers) -> a -> a

   snap-core	Snap.Internal.Core

   Modify the datatype's headers.

3. class HasHeaders a

   snap-core	Snap.Internal.Http.Types

   A typeclass for datatypes which contain HTTP headers.

4. addHeader :: HasHeaders a => CI ByteString -> ByteString -> a -> a

   snap-core	Snap.Internal.Http.Types

   Adds a header key-value-pair to the HasHeaders datatype. If a header with the same name already exists, the new value is appended to the headers list. Example:

   ghci> import qualified Snap.Types.Headers as H
   ghci> addHeader "Host" "localhost" H.empty
   H {unH = [("host","localhost")]}
   ghci> addHeader "Host" "127.0.0.1" it
   H {unH = [("host","localhost,127.0.0.1")]}
   

5. deleteHeader :: HasHeaders a => CI ByteString -> a -> a

   snap-core	Snap.Internal.Http.Types

   Clears a header value from a HasHeaders datatype. Example:

   ghci> import qualified Snap.Types.Headers as H
   ghci> deleteHeader "Host" $ setHeader "Host" "localhost" H.empty
   H {unH = []}
   

6. getHeader :: HasHeaders a => CI ByteString -> a -> Maybe ByteString

   snap-core	Snap.Internal.Http.Types

   Gets a header value out of a HasHeaders datatype. Example:

   ghci> import qualified Snap.Types.Headers as H
   ghci> getHeader "Host" $ setHeader "Host" "localhost" H.empty
   Just "localhost"
   

7. listHeaders :: HasHeaders a => a -> [(CI ByteString, ByteString)]

   snap-core	Snap.Internal.Http.Types

   Lists all the headers out of a HasHeaders datatype. If many headers came in with the same name, they will be catenated together. Example:

   ghci> import qualified Snap.Types.Headers as H
   ghci> listHeaders $ setHeader "Host" "localhost" H.empty
   [("host","localhost")]
   

8. rqHeaders :: Request -> Headers

   snap-core	Snap.Internal.Http.Types

   Contains all HTTP Headers associated with this request. Example:

   ghci> :set -XOverloadedStrings
   ghci> import qualified Snap.Test as T
   ghci> import qualified Data.Map as M
   ghci> rqHeaders `fmap` T.buildRequest (T.get "/foo/bar" M.empty)
   H {unH = [("host","localhost")]}
   

9. rspHeaders :: Response -> Headers

   snap-core	Snap.Internal.Http.Types

   No documentation available.

10. setHeader :: HasHeaders a => CI ByteString -> ByteString -> a -> a

    snap-core	Snap.Internal.Http.Types

    Sets a header key-value-pair in a HasHeaders datatype. If a header with the same name already exists, it is overwritten with the new value. Example:

    ghci> import qualified Snap.Types.Headers as H
    ghci> setHeader "Host" "localhost" H.empty
    H {unH = [("host","localhost")]}
    ghci> setHeader "Host" "127.0.0.1" it
    H {unH = [("host","127.0.0.1")]}
