95 <p>A long time ago, there was the <a href=
96 "http://www.junkbusters.com/ijb.html" target="_top"><span class=
97 "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders and
98 <a href="http://www.junkbusters.com/" target="_top">Junkbusters
99 Corporation</a>. This saved many users a lot of pain in the early days
100 of web advertising and user tracking.</p>
102 <p>But the web, its protocols and standards, and with it, the
103 techniques for forcing ads on users, give up autonomy over their
104 browsing, and for tracking them, keeps evolving. Unfortunately, the
105 <span class="APPLICATION">Internet Junkbuster</span> did not. Version
106 2.0.2, published in 1998, was (and is) the last official <a href=
107 "http://www.junkbusters.com/ijbdist.html#release" target=
108 "_top">release</a> available from <a href="http://www.junkbusters.com"
109 target="_top">Junkbusters Corporation</a>. Fortunately, it had been
110 released under the GNU <a href=
111 "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
112 "_top">GPL</a>, which allowed further development by others.</p>
114 <p>So Stefan Waldherr started maintaining an improved version of the
115 software, to which eventually a number of people contributed patches.
116 It could already replace banners with a transparent image, and had a
117 first version of pop-up killing, but it was still very closely based on
118 the original, with all its limitations, such as the lack of HTTP/1.1
119 support, flexible per-site configuration, or content modification. The
120 last release from this effort was version 2.0.2-10, published in
123 <p>Then, some <a href=
124 "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
125 "_top">developers</a> picked up the thread, and started turning the
126 software inside out, upside down, and then reassembled it, adding many
127 <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
128 target="_top">new features</a> along the way.</p>
130 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
131 whose first stable version, 3.0, was released August, 2002.</p>

240 <p>Privoxy is based in part on code originally developed by Junkbusters
241 Corp. and Anonymous Coders.</p>
243 <p>Privoxy heavily relies on Philip Hazel's PCRE.</p>
245 <p>The code to filter compressed content makes use of zlib which is
246 written by Jean-loup Gailly and Mark Adler.</p>
248 <p>On systems that lack snprintf(), Privoxy is using a version written
249 by Mark Martinec. On systems that lack strptime(), Privoxy is using the
250 one from the GNU C Library written by Ulrich Drepper.</p>
