// 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 its 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 its 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:
//
//      Open "Edit->Preferences"
//      Select "Advanced"
//      Select "Proxies"
//      Click "Clear Disk Cache"
//      Click "Clear Memory Cache"
//
// For Firefox:
//
//      Open "Tools->Options"
//      Select the "Privay" tab
//      Scroll down or go to the "Cache" section
//      Click "Clear"
//
// For Opera:
//
//      Open "File->Preferences"
//      Select "History and cache"
//      Click "Empty now"

// Other functions and methods that may work:
//      http://developer.netscape.com/docs/manuals/communicator/jsref/win1.htm
//      Note that "alert()" only works with Netscape4 and IE, and Mozilla 1.4+.
//
// NOTE:
//      isInNet() will resolve a hostname to an IP address, and cause
//      hangs on Mozilla/Firefox.  Currently, these are stubbed out and replaced
//      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

// Angus Turnbull pointed out the JavaScript 1.2 RE operators to me.
// These should work in NS4 and IE4 (or later), but I have only tested on
// Mozilla (1.3), IE5.5, and IE6.  PLEASE TELL ME IF IT WORKS FOR YOU!
//
// A good introduction is at:
//      http://www.evolt.org/article/Regular_Expressions_in_JavaScript/17/36435/
// Some references:
//      (old Netscape documentation is gone)

// Real-time evaluator:

// I'm slowly replacing multiple glob patterns with regexps.
// By using RE literals of /.../ rather than the constructor 'new RegExp()',
// the regexps should be compiled as no-ads.pac is loaded.
// 
// Important notes:
// -    if using the constructor, \ needs to be quoted; thus "\\." is used
//      to match a literal '.'.  In the RE literal form, I need to end up
//      quoting any / for a URL path.
// -    Avoid these for now; they are broken or not supported in "older"
