* Revisions :
* $Log: parsers.c,v $
+ * Revision 1.4 2001/05/22 18:46:04 oes
+ *
+ * - Enabled filtering banners by size rather than URL
+ * by adding patterns that replace all standard banner
+ * sizes with the "Junkbuster" gif to the re_filterfile
+ *
+ * - Enabled filtering WebBugs by providing a pattern
+ * which kills all 1x1 images
+ *
+ * - Added support for PCRE_UNGREEDY behaviour to pcrs,
+ * which is selected by the (nonstandard and therefore
+ * capital) letter 'U' in the option string.
+ * It causes the quantifiers to be ungreedy by default.
+ * Appending a ? turns back to greedy (!).
+ *
+ * - Added a new interceptor ijb-send-banner, which
+ * sends back the "Junkbuster" gif. Without imagelist or
+ * MSIE detection support, or if tinygif = 1, or the
+ * URL isn't recognized as an imageurl, a lame HTML
+ * explanation is sent instead.
+ *
+ * - Added new feature, which permits blocking remote
+ * script redirects and firing back a local redirect
+ * to the browser.
+ * The feature is conditionally compiled, i.e. it
+ * can be disabled with --disable-fast-redirects,
+ * plus it must be activated by a "fast-redirects"
+ * line in the config file, has its own log level
+ * and of course wants to be displayed by show-proxy-args
+ * Note: Boy, all the #ifdefs in 1001 locations and
+ * all the fumbling with configure.in and acconfig.h
+ * were *way* more work than the feature itself :-(
+ *
+ * - Because a generic redirect template was needed for
+ * this, tinygif = 3 now uses the same.
+ *
+ * - Moved GIFs, and other static HTTP response templates
+ * to project.h
+ *
+ * - Some minor fixes
+ *
+ * - Removed some >400 CRs again (Jon, you really worked
+ * a lot! ;-)
+ *
* Revision 1.3 2001/05/20 01:21:20 jongfoster
* Version 2.9.4 checkin.
* - Merged popupfile and cookiefile, and added control over PCRS
