Fixed bugs in HTTP_HEADERS::ParseInput()
Summary :
This file describes the files in the directory irtl\httphdr
and details related to HTTP Header Dictionary.
File Description
README.txt This file.
httphdr.hxx Header file containing declarations.
httphdr.cxx Implementation of Header Mapper and Header dictionary.
tdict.cxx Test program for Dictionary headers.
Implementation Details
Contents:
1. Design of Dictionary and Mapper
2. Replacements for old PARAM_LIST object in w3svc
1. Design of Dictionary and Mapper
class HTTP_HEADERS
class HTTP_HEADER_MAPPER
<To Be Done>
2. Replacements for old PARAM_LIST object in w3svc
O L D => N E W
HEADER_MAP::
Reset() => HTTP_HEADERS::Reset()
Store() => HTTP_HEADERS:FastMapStore()
Cancel() => HTTP_HEADERS:FastMapCancel()
MaxIndex() => HTTP_HEADERS::FastMapMaxIndex()
MaxMap() => HTTP_HEADER_MAPPER::NumItems()
CheckConcatAndStore() => HTTP_HEADERS::FastMapStoreWithConcat()
QueryStrValue() => HTTP_HEADERS::FastMapQueryStrValue()
QueryValue() => HTTP_HEADERS::FastMapQueryValue()
IsEmpty() => Nuked
PARAM_LIST::
Reset() => HTTP_HEADERS::Reset()
GetFastMap() => No need - use Fast map functions directly
FindValue() => HTTP_HEADERS::FindValue()
RemoveEntry() => CancelHeader()
AddEntryUsingConcat() => HTTP_HEADERS::StoreHeader()
AddEntry() => filter uses this - StoreHeader() is sufficient
-- rewriting code to check fast-map and op, is better
Enumerator functions:
NextPair() => are hard to achieve. Since the "header-name" is
not NULL terminated. We have to work-around this
by fixing the users of this call.
New Enumerators will return NAME_VALUE_PAIRS
FastMapEnumerate(),
ChunkEnumerator()
Nuked:
GetCount()
AddParam()
ParsePairs()
ParseSimpleList()
ParseHeaderList()
