ABOUT-----The Tomcat redirector was developed using Visual C++ Ver.6.0, so having this environment is a prerequisite if you want to perform a custom build.REQUIREMENT-----------* MS VC 6.0 (+ update, latest service pack is sp5)  isapi_redirector.dll can be built using the command line tools, or   from within the Visual Studio IDE Workbench. The command line build   requires the environment to reflect the PATH, INCLUDE, LIB and other   variables that can be configured with the vcvars32 batch file:     "c:\Program Files\DevStudio\VC\Bin\vcvars32.bat"* MS PLATFORM SDK  Visual C++ 6.0 builds require an updated Microsoft Windows Platform SDK   (http://www.microsoft.com/msdownload/platformsdk/sdkupdate/) to enable   some isapi_redirector.dll features. For command line builds,  the Platform SDK environment is prepared by the setenv batch file:    "c:\Program Files\Microsoft Platform SDK\setenv.bat"  Note that the Windows Platform SDK is only needed if you want authenticate   using IIS to compile a isapi_redirector.dll.. BUILDING-------- The steps that you need to take are:   1. Change directory to the isapi redirector plugins source directory.      2. Execute the following command:      MSDEV isapi.dsp /MAKE ALL      If msdev is not in your path, enter the full path to msdev.exeThis will build both release and debug versions of the redirector plugin.An alternative will be to open the isapi workspace file (isapi.dsw) in msdev and build it using the build menu.
