When Privoxy displays one of its internal - pages, such as a 404 Not Found error page - (Privoxy must be running for link to work as - intended), it uses the appropriate template. On Linux, BSD, and Unix, these - are located in /etc/privoxy/templates by default. These - may be customized, if desired. cgi-style.css is used to - control the HTML attributes (fonts, etc).
The default -Blocked -(Privoxy needs to be running for page to display) - banner page with the bright red top - banner, is called just "blocked". This - may be customized or replaced with something else if desired.
All Privoxy built-in pages, i.e. + error pages such as the "404 - No Such Domain" error page, + the "BLOCKED" page and all pages + of its web-based user + interface, are generated from templates. (Privoxy must be running for the above links to work + as intended.)
+ +These templates are stored in a subdirectory of the configuration directory called templates. On Unixish platforms, this is typically + /etc/privoxy/templates/.
+ +The templates are basically normal HTML files, but with place-holders + (called symbols or exports), which Privoxy fills at run time. It is possible to edit + the templates with a normal text editor, should you want to customize + them. (Not recommended for the + casual user). Should you create your own custom templates, you + should use the config setting templdir to specify an alternate location, so + your templates do not get overwritten during upgrades.
+ +Note that just like in configuration files, lines starting with + # are ignored when the templates are filled + in.
+ +The place-holders are of the form @name@, and + you will find a list of available symbols, which vary from template to + template, in the comments at the start of each file. Note that these + comments are not always accurate, and that it's probably best to look at + the existing HTML code to find out which symbols are supported and what + they are filled in with.
+ +A special application of this substitution mechanism is to make whole + blocks of HTML code disappear when a specific symbol is set. We use this + for many purposes, one of them being to include the beta warning in all + our user interface (CGI) pages when Privoxy is in an alpha or beta development + stage:
+ +
+ +<!-- @if-unstable-start --> + + ... beta warning HTML code goes here ... + +<!-- if-unstable-end@ --> ++ |
+
If the "unstable" symbol is set, everything in between and including + @if-unstable-start and if-unstable-end@ will disappear, leaving nothing but an + empty comment:
+ +
+ +<!-- --> ++ |
+
There's also an if-then-else construct and an #include mechanism, but you'll sure find out if you are + inclined to edit the templates ;-)
+ +All templates refer to a style located at http://config.privoxy.org/send-stylesheet. This is, of + course, locally served by Privoxy and + the source for it can be found and edited in the cgi-style.css template.
