From 5f6ae94ad0163341c2cd79a89f29b2187367b5ba Mon Sep 17 00:00:00 2001 From: Rob Shearman Date: Wed, 18 Mar 2009 11:13:19 +0000 Subject: [PATCH] rpcrt4: Implement RPC over HTTP support. CodeWeavers did this work for supporting the optional HTTP connection method of Outlook 2003/2007 (must be running with Windows versions set to XP or higher to see this option). This was written before Microsoft publicly released a specification for the RPC over HTTP protocol and so was developed by examining traffic flowing between a Windows client and an IIS server. --- dlls/rpcrt4/Makefile.in | 2 +- dlls/rpcrt4/rpc_assoc.c | 1 + dlls/rpcrt4/rpc_assoc.h | 1 + dlls/rpcrt4/rpc_binding.h | 3 + dlls/rpcrt4/rpc_defs.h | 10 + dlls/rpcrt4/rpc_message.c | 332 ++++++++++++++- dlls/rpcrt4/rpc_message.h | 11 + dlls/rpcrt4/rpc_transport.c | 994 +++++++++++++++++++++++++++++++++++++++++++- 8 files changed, 1337 insertions(+), 17 deletions(-) diff --git a/dlls/rpcrt4/Makefile.in b/dlls/rpcrt4/Makefile.in index b44bfb0f56a..3e47345636d 100644 --- a/dlls/rpcrt4/Makefile.in +++ b/dlls/rpcrt4/Makefile.in @@ -6,7 +6,7 @@ VPATH = @srcdir@ MODULE = rpcrt4.dll IMPORTLIB = rpcrt4 IMPORTS = uuid advapi32 kernel32 ntdll -DELAYIMPORTS = secur32 user32 +DELAYIMPORTS = wininet secur32 user32 C_SRCS = \ cproxy.c \ diff --git a/dlls/rpcrt4/rpc_assoc.c b/dlls/rpcrt4/rpc_assoc.c index c9bf7c91787..256edb24a00 100644 --- a/dlls/rpcrt4/rpc_assoc.c +++ b/dlls/rpcrt4/rpc_assoc.c @@ -394,6 +394,7 @@ RPC_STATUS RpcAssoc_GetClientConnection(RpcAssoc *assoc, if (status != RPC_S_OK) return status;
