+// This simple kludge uses a mechanism built into most browsers (IE, Netscape,
+// Mozilla, Firefox, and Opera) on most platforms to block connections to
+// banner ad servers.
+//
+// This mechanism uses the "proxy auto configuration" to blackhole requests
+// to load ad images without forcing all your traffic through an ad-blocking
+// proxy server.  Of course, unlike ad-blocking proxy servers, this does not
+// otherwise not strip cookies.
+//
+// "Proxy auto configuration" invokes the JavaScript FindProxyForURL function
+// below each time your browser requests a URL.  This works even if you have
+// JavaScript otherwise disabled in your browser!  (Which you should!)

+//
+// These are the basic steps needed to use "no-ads.pac".
+// Detailed instructions follow below!
+//
+// 1. Save this as a file (no-ads.pac) on your local disk
+//    (or, add it to your home page, if you have one)
+// 2. Select a no-ads "blackhole".
+// 3. Configure your browser to use this file as it's auto proxy configuration.
+// 4. Clear your browser's cache
+//    (or else it may still show you ads it has saved on your disk).
+//
+
+
+///////////////////////////////////////////////////////////////////////////////
+//
+// 1. SAVE THIS FILE
+//
+// Copy this file to your local machine; use your home directory (UNIX)
+// or your Desktop or C:\ directory (Windows).
+//
+
+
+
+///////////////////////////////////////////////////////////////////////////////
+//
+// 2. SELECT A NO-ADS BLACKHOLE
+//
+// You can skip this section if you are using any version of Internet Explorer.
+// You can also skip this section for Netscape 7.1, Mozilla 1.4, or
+// Firefox 1.0 (or later), as they include PAC failover support (but do
+// read the note in section "2a" below).
+//
+//
+// The basic trick of no-ads is to match the site or URL of annoying web content
+// and tell your browser to use a proxy that will deny loading of that resource
+// (image, page, etc).
+//
+// A "black-hole" proxy server is one that always denies loading a web page.
+// ("send it off to a blackhole").
+//
+// When you initially get "no-ads.pac", it is using this as the blackhole:
+//
+//      "PROXY 0.0.0.0:3421"
+//
+// This says to use the local host at a port which nothing should be listening
+// on.  Thus, this is "a server that doesn't repond."
+//
+// This is a good default for all systems, and especially Windows.
+// However, if you are using the Blackhole Proxy Server on Windows, 
+// be sure to change it to "PROXY 127.0.0.1:3421"
+//
+//
+// Some possibilities for the blackhole:
+//
+//      a. A server that doesn't respond.
+//
+//              *** This works for all versions of Internet Explorer.
+//              *** This mostly works for Mozilla, Firefox, and Netscape.
+//
+//              If you do nothing, then this is configured to direct annoying
+//              content to the proxy running on your own host at port 3421.
+//              Since you shouldn't have anything running on that port, that
+//              connection will timeout and the annoying content will never be
+//              loaded.
+//
+//              Older versions of Netscape wait to connect to the proxy server
+//              (usually it needs to load part of the image to layout the web
+//              page), and then asks if you want to disable the proxy that
+//              doesn't answer.
+//
+//              Older versions of Mozilla will give an alert saying it couldn't
+//              connect to the proxy server.
+//
+//              Mozilla 1.4+, Firefox 1.0+ and Netscape 7.1 will only give
+//              you this alert if the whole page being display is blocked,
+//              rather than just an image on that page.  Thus, I still
+//              recommend a blackhole proxy even though it isn't needed.
+//
+//              Opera will disable your auto proxy config if the proxy server
+//              doesn't respond.
+//
+//              IE doesn't care that the proxy server isn't responding.  As
+//              this avoids a connection for annoying content, it is fastest.
+//
+//      b. A simple, blackhole server
+//
+//              When needed, I run a simple "server" at port 3421 that denies
+//              all requests.  Some options you can use for this:
+//
+//              - On Windows, you can try Larry Wang's black-hole proxy program:
+//
+//                      http://leisuresuit10.tripod.com/BlackHoleProxy/
+//
+//                I can not vouch that his binaries are virus free, but he does
+//                offer the source code.
+//
+//              - I use this shell script on UNIX; it is invoked via inetd.
+//                /usr/local/lib/noproxy:
+//
+//                      #!/bin/sh
+//                      read a
+//                      read b
+//                      echo HTTP/1.0 501 No Ads Accepted
+//                      echo ""
+//                      exit
+//
+//                Add this line to inetd.conf ('kill -HUP' inetd afterwards):
+//
+//                  3421 stream tcp nowait nobody /usr/local/lib/noproxy noproxy
+//
+//                This simple script doesn't work on Linux because of the
+//                (IMHO) broken way it's TCP stack works.  See the bottom of
+//                http://www.schooner.com/~loverso/no-ads/ for a complete copy
+//                of the `noproxy' shell script.
+//
+//                If always exec'ing a shell was expensive on your computer
+//                (it isn't on mine), then you could use a "wait"-style Perl
+//                script that would accept() incoming connections.
+//
+//              - Sean Burke has a black-hole proxy written in Perl script:
+//
+//                http://www.speech.cs.cmu.edu/~sburke/pub/black_hole_http_server.pl
+//                (This is a standalone server, not run from inetd).
+//
+//      e. A trick: use an HTTP/1.0 non-proxy server
+//
+//              An HTTP/1.0 non-proxy server will return a 501 error when
+//              given a proxy request.  Thus, just use the address of your
+//              local intranet web server as your blackhole PROXY.
+//              The downside of this is that it will probably also log an
+//              error, which wastes a small amount of resources.
+//
+//      ***
+//      *** Be sure to update the "blackhole" variable above with a setting of
+//      *** "PROXY hostname:port" that matches your blackhole server!!
+//      ***
+//
+//      ***
+//      *** If you already use a proxy server to access the WWW,
+//      *** change the "normal" variable above from "DIRECT" to
+//      *** be "PROXY proxy:port" to match your proxy server.

+//
+// 3. TO CONFIGURE YOUR BROWSER
+//
+// The Proxy Auto Configuration file can be either on the local disk or
+// accessed from a web server, with the following constraints:
+//
+//      a. IE4 can only load the PAC from a web server (http:// URL)
+//      b. Netscape, Mozilla, Firefox and IE (5 or later) can load the
+//         PAC from anywhere.
+//      c. Netscape, Mozilla, Firefox and (probably) Opera require the correct
+//         MIME type when loading the PAC from a web server.
+//
+//
+// To set the Proxy Auto Configuration with Netscape, Mozilla, or Firefox:
+//
+//   1. Enable Proxy Auto Config:
+//
+//      For Netsacpe/Mozilla:
+//
+//              Open "Edit->Preferences"
+//              Select "Advanced"
+//              Select "Proxies"
+//
+//      For Firefox (1.0):
+//
+//              Open "Tools->Options"
+//              Select "Coonection Settings" on the General tab:
+//
+//      Select the "Auto proxy configuration URL" option.
+//      Enter URL or path of where you've saved this file, such as:
+//
+//              http://yourserver/no-ads.pac
+//
+//      If you place this on your local disk, you should use a
+//      file: URL such as:
+//
+//              file:/home/loverso/no-ads.pac                   (UNIX)
+//              file:///c:/windows/desktop/no-ads.pac           (Windows)
+//
+//      (file:/ and file:// will work in Mozilla, but file:/// is correct
+//      required for Firefox)
+//
+//   2. If you are serving this from a web server, these browsers require
+//      the correct MIME type on the file before using it.  You must configure
+//      your web server to provide a "application/x-ns-proxy-autoconfig"
+//      MIME type.
+//
+//      a. For Apache, name the file with a ".pac" extension and add this
+//         line to the http.conf (or the .htaccess file in the same directory):
+//
+//              AddType application/x-ns-proxy-autoconfig .pac
+//
+//      b. For IIS (instructions from Kevin Roth)
+//
+//         Open Internet Services Manager
+//         Right click on the web site (or directory) you wish to change.
+//         Choose Properties
+//         Click the "HTTP Headers" tab
+//         Click the "File Types" button in the "MIME Map" section
+//         Click the "New Type..." button
+//         Enter "pac" for "Associated Extension"
+//         Enter "application/x-ns-proxy-autoconfig" for "Content Type (MIME)"
+//         Click OK to close the Add type dialog, the MIME types dialog,
+//              and the main properties dialog.
+//
+//      (This is definately needed for NS, but not for IE)
+//
+//
+// To set the Proxy Auto Configuration with IE:
+//
+//   1. Enable Proxy Auto Config:
+//
+//      Open "Tools->Internet Options"
+//      Select "Connections" tab
+//      Click "LAN Settings"
+//              or Choose an entry from "Dial-up settings" and click "Settings"
+//
+//      On the settings dialog, select "Use automatic configuration script"
+//      Enter the URL of this file in Address field.
+//
+//              http://yourserver/no-ads.pac
+//              file:///c:/windows/desktop/no-ads.pac           (Windows)
+//
+//      You can only use a file: URL with IE5 (or later).
+//      ("file:///" with with IE versions after 5.0 SP2)
+//
+//   2. Fix Security Settings (IMPORTANT):
+//
+//      Select "Security" tab
+//      Select "Local intranet"
+//      Click "Sites" box
+//      Unselect "include all sites that bypass the proxy server" option
+//
+//   3. Disable "Auto Proxy Caching" (IMPORTANT):
+//      (thanks to Kevin Roth for alerting me of this!)
+//
+//      IE contains a proxy result caching mechanism that will defeat the
+//      ability to block servers that server both ad and non-ad content.
+//      To prevent this, add the registry key described in this MS KB article:
+//
+//              http://support.microsoft.com/?kbid=271361
+//
+//      You can do so by downloading this file and clicking on it to load
+//      it into the registry.  This must be done on a per-user basis.
+//      http://www.schooner.com/~loverso/no-ads/IE-no-auto-proxy-cache.reg
+//
+//   IE doesn't currently check the MIME type of the PAC file.
+//
+//   To see some notes from MS on PAC in IE, see
+//      http://msdn.microsoft.com/library/periodic/period99/faq0599.htm
+//      (they seem to have removed this URL)
+//
+//
+// To set the Proxy Auto Configuration with Opera 6 (6.04 on Windows tested):
+//
+//   1. Enable Proxy Auto Config:
+//      Open the Preferences (Alt-P)
+//      Select "Network"
+//      Click the "Proxy servers" box
+//      Select "Use automatic proxy configuration"
+//      Enter the URL of this file as
+//
+//              http://yourserver/no-ads.pac
+//              file://c:/windows/desktop/no-ads.pac
+//
+//      (file:/// might be needed; I've not tested Opera lately)
+//
+//   2. You must use a blackhole proxy for Opera (it will not work with an
+//      address of a server that does not respond).
+//
+//   3. Be sure to clear the cache and exit/restart Opera.
+//
+
+

+//
+// 4. CLEAR YOUR BROWSER'S CACHE
+//
+// For Internet Explorer:
+//
+//      Open "Tools->Internet Options"
+//      Select "Delete Files" under "Temporary Internet Files"
+//      Click "OK"
+//
+// For Mozilla/Netscape Navigator:

+//
+// NOTE:
+//      isInNet() will resolve a hostname to an IP address, and cause

+//      with shExpMatch(host, "a.b.c.*"), which doesn't do the same thing,
+//      but is sufficient for these purposes.
+//
+// Additional Mozilla/Firefox comments:
+//
+//      All the above PAC functions are implemented in JavaScript,
+//      and are added to the body of your PAC file when it is loaded.
+//      See the "components/nsProxyAutoConfig.js" browser install
+//      directory.
+//
+//      - shExpMatch() is implemented as three pattern.replaces()
+//               followed by a call to RegExp()  (SLOW)
+//      - isPlainHostname() just checks for lack of "." in the string
+//      - dnsDomainIs() just matches strings exactly
+//      - alert() is bound to this.proxyAlert(), which displays a message
+//              in the JavaScript console window
