![]() In fact, waiting around for your sites to download is the most annoying thing about Web Dumper but with pages containing so much content nowadays, it can be forgiven for that. As you can imagine, for sites that are contain huge media files, this can take a rather long time. So the following filter simply says "replace any occurrence of the HTML between the 1st and 2nd pipes with whatever is between the 2nd and 3rd pipes".Web Dumper automatically downloads HTML documents along with their embedded pictures, sounds, movies etc. In these cases we have Privoxy rewrite specific HTML before providing it to the users in order to route them through a transparent proxy server that the Library uses for off-campus access to the databases. For example, some of the databases that the Library subscribes to will not work with Privoxy via the standard means of entering URLs in the config file. You can toggle the effect of actions and filters with a + (enabled) or a - (disabled)ĭefault.filter: this is where you tell Privoxy to rewrite actual content on web sites. This was blocking a legitimate image that happened to be the right size, so I had to track down which filter was doing this and disable it (it was the, to name just a few of the many. ![]() the standard size of an advertising banner. One problem I had is that Privoxy is set by default to block images if they are a certain size - i.e. By default this file has tons of actions enabled that you will need to experiment with. Privoxy will re-read the config file when it notices that changes have been made, which will cause a brief proxy outage while it looks up each of the addresses in the config file.ĭefault.action: the list of actions that Privoxy will apply to URLs. We have to figure out every server that is hit for an individual database and add it to our config file for each of our subnets (a great utility for finding all servers used on a web page is DeepVacuum ). Some problems we continue to experience are databases that use redirects to other servers, or store images on different servers, or use a different server for searches, etc. Since we need to allow access not only to Library pages, but also hundreds of database sites that the U subscribes to, our config file has gotten enormous. Also note that you can simply edit the settings files with a text editor if you disable the web interface. There you can view all of and edit some of your action/filter files and config file, toggle options on and off, and look up what actions/filters will be applied to a specific URL. ![]() Web Interface: You can access the web interface on a proxy-enabled machine using or the shortcut. You need to enter a few things in its primary settings file - the config file discussed below - before you can start using it as a proxy server. ![]() pkg installer, and is installed in /Library/Privoxy, as well as an item in /Library/StartupItems to ensure it is turned on at system startup. ![]() But once you've got it customized it is very stable and easy to maintain. The default installation has enabled tons of filters, ad and cookie blockers, etc - and you will need to adjust many of these to make it do what you want. Privoxy is very straightforward to install, although it takes a lot of time to tweak it just the way you want it. Configuration & Features We began using Privoxy in the Library as a solution for limiting internet access to specific sites on kiosk Macs throughout the library, since all other public computers began requiring users to log in to get full internet access. ![]()
