Revision 2.1 2002/06/04 17:22:36 jongfoster Adding comments

Revision 2.0 2002/06/04 14:34:21 jongfoster Moving source files to src/

Revision 1.13 2002/03/26 22:29:54 swa we have a new homepage!

Revision 1.12 2002/03/24 13:25:43 swa name change related issues

Revision 1.11 2002/03/06 23:02:57 jongfoster Removing tabs

Revision 1.10 2001/09/13 20:08:06 jongfoster Adding support for LOG_LEVEL_CGI

Revision 1.9 2001/07/30 22:08:36 jongfoster Tidying up defines:

• All feature defines are now of the form FEATURE_xxx
• Permanently turned off WIN_GUI_EDIT
• Permanently turned on WEBDAV and SPLIT_PROXY_ARGS

Revision 1.8 2001/07/29 18:43:08 jongfoster Changing ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to ANSI C rules.

Revision 1.7 2001/07/19 19:02:53 haroon Added define for LOG_LEVEL_POPUPS

Revision 1.6 2001/07/13 13:59:22 oes

• Added LOG_LEVEL_DEANIMATE
• Changed LOG_LEVEL_CLF
• Removed all ifdef PCRS

Revision 1.5 2001/05/26 17:25:14 jongfoster Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG

Revision 1.4 2001/05/25 21:56:06 jongfoster Added FIXME comment to (broken) LOG_LEVEL_LOG

Revision 1.3 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 1.2 2001/05/20 01:11:40 jongfoster Added support for LOG_LEVEL_FATAL Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE, and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER

Revision 1.1.1.1 2001/05/15 13:58:51 oes Initial import of version 2.9.3 source tree
