- <h3><img class="title" src="../shared_images/local_activity_blue_light.png"> Resource Requests</h3>
-
- <p>When a URL is loaded, it typically makes a number of resource requests for CCS, JavaScript, image, and other files. Details about these requests can be viewed in the Requests activity.
- The navigation drawer has a link to the Requests activity and also shows how many requests were blocked. Tapping on a request displays details about why it was allowed or blocked.</p>
-
- <p><img class="center" src="images/request_details.png"></p>
-
- <p>Privacy Browser includes four <a href="https://easylist.to/">common blocklists</a> based on the <a href="https://adblockplus.org/filters">Adblock syntax</a>:
- EasyList, EasyPrivacy, Fanboy’s Annoyance List, and Fanboy’s Social Blocking List.
- These blocklists are processed by Privacy Browser into the following 22 sublists, which check resource requests in the order listed.</p>
-
- <ol>
- <li>Main Whitelist</li>
- <li>Final Whitelist</li>
- <li>Domain Whitelist</li>
- <li>Domain Initial Whitelist</li>
- <li>Domain Final Whitelist</li>
- <li>Third-Party Whitelist</li>
- <li>Third-Party Domain Whitelist</li>
- <li>Third-Party Domain Initial Whitelist</li>
- <li>Main Blacklist</li>
- <li>Initial Blacklist</li>
- <li>Final Blacklist</li>
- <li>Domain Blacklist</li>
- <li>Domain Initial Blacklist</li>
- <li>Domain Final Blacklist</li>
- <li>Domain Regular Expression Blacklist</li>
- <li>Third-Party Blacklist</li>
- <li>Third-Party Initial Blacklist</li>
- <li>Third-Party Domain Blacklist</li>
- <li>Third-Party Domain Initial Blacklist</li>
- <li>Third-Party Regular Expression Blacklist</li>
- <li>Third-Party Domain Regular Expression Blacklist</li>
- <li>Regular Expression Blacklist</li>
- </ol>
-
- <p>Initial lists check against the beginning of the URL. Final lists check against the end of the URL. Domain lists only check against certain domains.
- Third-party lists only apply if the root domain of the request is different than the root domain of the main URL.
- Regular expression lists follow the <a href="https://en.wikipedia.org/wiki/Regular_expression">regular expression syntax</a>. Each sublist item has one or more entry.
- In the case of domain sublists, the resource request is only checked against the item if the first entry matches the domain of the main URL.</p>
-
- <p>Because of limitations in Android’s WebView, and to speed up processing of requests, Privacy Browser implements a simplified interpretation of the Adblock syntax.
- This can sometimes lead to false positives, where resources are allowed or blocked in ways that weren’t intended by the original entry.
- A more detailed description of how the blocklist entries are processed is available at <a href="https://www.stoutner.com/privacy-browser/blocklists/">stoutner.com</a>.</p>
-
- <p>Privacy Browser has three additional blocklists.
- <a href="https://www.stoutner.com/privacy-browser/blocklists/ultralist/">UltraList</a> and <a href="https://www.stoutner.com/privacy-browser/blocklists/ultraprivacy/">UltraPrivacy</a>
- block ads and trackers that EasyList and EasyPrivacy do not. The third blocks all third-party requests.
- A request is only considered third-party if the base domain of the request is different than the base domain of the URL.
- For example, if <code>www.website.com</code> loads a picture from <code>images.website.com</code>,
- this is not blocked as a third-party request because they both share the same base domain of <code>website.com</code>.
- Blocking all third-party requests increases privacy, but this blocklist is disabled by default because it breaks a large number of websites.</p>
