82 <p>A long time ago, there was the <a href=
83 "http://www.junkbusters.com/ijb.html" target="_top"><span class=
84 "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders and
85 <a href="http://www.junkbusters.com/" target="_top">Junkbusters
86 Corporation</a>. This saved many users a lot of pain in the early days
87 of web advertising and user tracking.</p>
89 <p>But the web, its protocols and standards, and with it, the
90 techniques for forcing ads on users, give up autonomy over their
91 browsing, and for tracking them, keeps evolving. Unfortunately, the
92 <span class="APPLICATION">Internet Junkbuster</span> did not. Version
93 2.0.2, published in 1998, was (and is) the last official <a href=
94 "http://www.junkbusters.com/ijbdist.html#release" target=
95 "_top">release</a> available from <a href="http://www.junkbusters.com"
96 target="_top">Junkbusters Corporation</a>. Fortunately, it had been
97 released under the GNU <a href=
98 "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
99 "_top">GPL</a>, which allowed further development by others.</p>
101 <p>So Stefan Waldherr started maintaining an improved version of the
102 software, to which eventually a number of people contributed patches.
103 It could already replace banners with a transparent image, and had a
104 first version of pop-up killing, but it was still very closely based on
105 the original, with all its limitations, such as the lack of HTTP/1.1
106 support, flexible per-site configuration, or content modification. The
107 last release from this effort was version 2.0.2-10, published in
110 <p>Then, some <a href=
111 "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
112 "_top">developers</a> picked up the thread, and started turning the
113 software inside out, upside down, and then reassembled it, adding many
114 <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
115 target="_top">new features</a> along the way.</p>
117 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
118 whose first stable version, 3.0, was released August, 2002.</p>

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