And sometimes we need to be able to + see just what Privoxy is + doing. Especially, if something Privoxy is doing + is causing us a problem inadvertantly. It can be a little daunting to look at + the actions and filters files themselves, since they tend to be filled with + regular expressions whose consequences are not always + so obvious. Privoxy provides the + http://config.privoxy.org/show-url-info + page that can show us very specifically how actions + are being applied to any given URL. This is a big help for troubleshooting. + + + + First, enter one URL (or partial URL) at the prompt, and then + Privoxy will tell us + how the current configuration will handle it. This will not + help with filtering effects from the default.filter file! It + also will not tell you about any other URLs that may be embedded within the + URL you are testing. For instance, images such as ads are expressed as URLs + within the raw page source of HTML pages. So you will only get info for the + actual URL that is pasted into the prompt area -- not any sub-URLs. If you + want to know about embedded URLs like ads, you will have to dig those out of + the HTML source. Use your browser's View Page Source option + for this. Or right click on the ad, and grab the URL. + + + + Let's look at an example, google.com, + one section at a time: + + + + + System default actions: + + { -add-header -block -deanimate-gifs -downgrade -fast-redirects -filter + -hide-forwarded -hide-from -hide-referer -hide-user-agent -image + -image-blocker -limit-connect -no-compression -no-cookies-keep + -no-cookies-read -no-cookies-set -no-popups -vanilla-wafer -wafer } + + + + + + This is the top section, and only tells us of the compiled in defaults. This + is basically what Privoxy would do if there + were not any actions defined, i.e. it does nothing. Every action + is disabled. This is not particularly informative for our purposes here. OK, + next section: + + + + + + Matches for http://google.com: + + { -add-header -block +deanimate-gifs -downgrade +fast-redirects + +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups} + +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal} + +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge} + -hide-user-agent -image +image-blocker{blank} +no-compression + +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups + -vanilla-wafer -wafer } + / + + { -no-cookies-keep -no-cookies-read -no-cookies-set } + .google.com + + { -fast-redirects } + .google.com + + + + + + This is much more informative, and tells us how we have defined our + actions, and which ones match for our example, + google.com. The first grouping shows our default + settings, which would apply to all URLs. If you look at your actions + file, this would be the section just below the aliases section + near the top. This applies to all URLs as signified by the single forward + slash -- /. + + + + + These are the default actions we have enabled. But we can define additional + actions that would be exceptions to these general rules, and then list + specific URLs that these exceptions would apply to. Last match wins. + Just below this then are two explict matches for .google.com. + The first is negating our various cookie blocking actions (i.e. we will allow + cookies here). The second is allowing fast-redirects. Note + that there is a leading dot here -- .google.com. This will + match any hosts and sub-domains, in the google.com domain also, such as + www.google.com. So, apparently, we have these actions defined + somewhere in the lower part of our actions file, and + google.com is referenced in these sections. + + + + + And now we pull it altogether in the bottom section and summarize how + Privoxy is appying all its actions + to google.com: + + + + + + + Final results: + + -add-header -block -deanimate-gifs -downgrade -fast-redirects + +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups} + +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal} + +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge} + -hide-user-agent -image +image-blocker{blank} -limit-connect +no-compression + -no-cookies-keep -no-cookies-read -no-cookies-set +no-popups -vanilla-wafer + -wafer + + + + + + Now another example, ad.doubleclick.net: + + + + + + { +block +image } + .ad.doubleclick.net + + { +block +image } + ad*. + + { +block +image } + .doubleclick.net + + + + + + We'll just show the interesting part here, the explicit matches.

The custom alias +imageblock does this + for us. + + + + One last example. Let's try http://www.rhapsodyk.net/adsl/HOWTO/. + This one is giving us problems. We are getting a blank page. Hmmm... + + + + + + Matches for http://www.rhapsodyk.net/adsl/HOWTO/: + + { -add-header -block +deanimate-gifs -downgrade +fast-redirects + +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups} + +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal} + +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge} + -hide-user-agent -image +image-blocker{blank} +no-compression + +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups + -vanilla-wafer -wafer } + / + + { +block +image } + /ads + + + + + + Ooops, the /adsl/ is matching /ads! But + we did not want this at all! Now we see why we get the blank page. We could + now add a new action below this that explictly does not + block (-block) pages with adsl. There are various ways to + handle such exceptions. Example: + + + + + + { -block } + /adsl + + + + + + Now the page displays ;-) Be sure to flush your browser's caches when + making such changes. Or, try using Shift+Reload. + + + + But now what about a situation where we get no explicit matches like + we did with: + + + + + + { -block } + /adsl + + + + + + That actually was very telling and pointed us quickly to where the problem + was. If you don't get this kind of match, then it means one of the default + rules in the first section is causing the problem. This would require some + guesswork, and maybe a little trial and error to isolate the offending rule. + One likely cause would be one of the {+filter} actions. Try + adding the URL for the site to one of aliases that turn off +filter: + + + + + + {shop} + .quietpc.com + .worldpay.com # for quietpc.com + .jungle.com + .scan.co.uk + .forbes.com + + + + + + {shop} is an alias that expands to + { -filter -no-cookies -no-cookies-keep }. Or you could do + your own exception to negate filtering: + + + + + + + {-filter} + .forbes.com + + + + + + {fragile} is an alias that disables most actions. This can be + used as a last resort for problem sites. Remember to flush caches! If this + still does not work, you will have to go through the remaining actions one by + one to find which one(s) is causing the problem. + + + +
