• Web.py is installed by “Easy Install” as Python eggs.
• To install “Easy Install”(setuptools), download ez_setup.py, run it, setuptools egg for right Python version is installed automatically.
• Run “ez_setup.py web.py”, web.py is installed automatically.
• web.py implements WSGI. Need to install flup to provide WSGI interfaces for web.py and web server as CGI, FastCGI or SCGI.
• Config Apache to allow CGI on web directory. Most common problem is permission setting, but its fare easy on Windows.
• Problem exists with flup to run under such environment. Blow logs could be found in Apache err log

Modification to flup code and repack is needed.

Down load flup code (but by ez_setup).
Modify fcgi_base.py as:

    def _setupSocket(self):
        if self._bindAddress is None: # Run as a normal FastCGI?
            isFCGI = True

            #@ commented by charlie, ref: http://groups.google.com/group/webpy/browse_thread/thread/67a8cfa5fdb1882b/722acab404514de4
##             sock = socket.fromfd(FCGI_LISTENSOCK_FILENO, socket.AF_INET,
##                                  socket.SOCK_STREAM)
##             try:
##                 sock.getpeername()
##             except socket.error, e:
##                 if e[0] == errno.ENOTSOCK:
##                     # Not a socket, assume CGI context.
##                     isFCGI = False
##                 elif e[0] != errno.ENOTCONN:
##                     raise
            isFCGI = False

            # FastCGI/CGI discrimination is broken on Mac OS X.

Rebuild eggs for flup following the easy instructions, run “setup.py bdist_egg“.
Copy the new egg to site-packages directory.

My things done.
