This dir has our ISAPI ! # extension as the only application, mapped to file-extension '*'. Thus, our ! # extension handles *all* requests in this directory. ! # The basic process is that the filter does URL rewriting, redirecting every ! # URL to our Virtual Directory. Our extension then handles this request, ! # forwarding the data from the proxied site. ! # So, the process is: ! # * URL of "index.html" comes in. ! # * Filter rewrites this to "/python/index.html" ! # * Our extension sees the full "/python/index.html", removes the leading ! # portion, and opens and forwards the remote URL. ! ! # This sample is very small - it avoid most error handling, etc. It is for ! # demonstration purposes only. from isapi import isapicon, threaded_extension - from isapi.simple import SimpleFilter import sys import traceback ! import urllib # sys.isapidllhandle will exist when we are loaded by the IIS framework. --- 9,25 ---- # this module and create your Extension and Filter objects. ! # This is the simplest possible redirector (or proxy) we can write.
