Update of /cvsroot/ijbswa/current
In directory sfp-cvs-1.v30.ch3.sourceforge.com:/tmp/cvs-serv6270
Modified Files:
GNUmakefile.in cgi.c cgisimple.c cgisimple.h configure.in
filters.c filters.h jcc.c jcc.h loadcfg.c project.h urlmatch.c
Log Message:
Implement client-specific tags
... which allow Privoxy admins to pre-define tags that
are set for all requests from clients that previously
opted-in through the CGI interface.
They are useful in multi-user setups where admins may
want to allow users to disable certain actions and filters
for themselves without affecting others.
In single-user setups they are useful to allow more
fine-grained toggling. For example to disable request
blocking while still crunching cookies, or to disable
experimental filters only.
This is an experimental feature, to enable it configure
with --enable-client-tags. The syntax and behaviour may
change in future versions.
Implements TODO list item #144 and #145.
Funded by a donation from Robert Klemme.
