type Limit = Int

Message header size limit in bytes.

readMessageHeader :: Limit -> Connection -> IO (ByteString, [Header])

Read start-line and message headers from provided Connection (see RFC 2616, Section 4.1).

Throws:

• HeaderTooLarge if start-line and headers together exceed the specified size Limit
• InvalidHeader if start-line is missing or a header is malformed

defaultHeaderSizeLimit :: Limit

The default message header size limit of 65536 bytes (64 KB).

parseHeaderFields :: [ByteString] -> Maybe [Header]

Parse header fields according to RFC 2616, Section 4.2.

sendHeader :: (ByteString -> IO ()) -> ByteString -> [Header] -> IO ()

Send given start-line and message headers.

Note: The first argument to this function is used to send the data. For space efficiency it may be called multiple times.
