\begin_layout Quote
Perhaps the most important security concept within modern browsers is the
 idea of the same-origin policy.
 The principal intent for this mechanism is to make it possible for largely
 unrestrained scripting and other interactions between pages served as a
 part of the same site (understood as having a particular DNS host name,
 or part thereof), whilst almost completely preventing any interference
 between unrelated sites.

Some brokers categorize consumers as "Getting By," "Compulsive Online Gamblers"
 and "Zero Mobility" and advertise the lists as ideal leads for banks, credit-ca
rd issuers and payday and subprime lenders, according to a review of data
 brokers' websites.
 One company offers lists of "Underbanked Prime Prospects" broken down by
 race.
 Others include "Kaching! Let it Ride Compulsive Online Gamblers" and "Speedy
 Dinero," described as Hispanics in need of fast cash receptive to subprime
 credit offers.

 NOTE: This data is generated by using the ISO 3166 economy code information
 provided in the allocation and assignment statistics reports as generated
 by the Regional Internet Registries.
 This code reflects the economy in which the entity to whom the allocation
 or assignment was made is located, but does not necessarily reflect the
 scope of use of deployment of the associated resource.
 Many Internet service networks have international components, and their
 numbering resources are often deployed across multiple economies.
 For this reason the report presented here does not accurately reflect the
 actual number resource distributions across these economies.

\begin_layout Section
External resources
\end_layout

\begin_layout Quote
Several popular Web sites have a significant component of extraneous material.
 This material includes advertisements, user-related data gathering mechanisms
 and flash animations.
 Such non-essential parts of the page sought by downloaders can be viewed
 as 
\emph on
extraneous
\emph default
 content from the perspective of the user and thus potentially undesirable.
 However, from the content owner's viewpoint, such material is integral
 for delivering content of interest to subsets of users.

\begin_layout Quote
Popular sites on the Web routinely include extraneous content.
 Part of the extraneous content may be small images or specific script routines
 used to detect subsequent click access.
 Even without registration many Web sites gather information about users
 via traditional mechanisms such as cookies, tracking navigation patterns
 via the

 HTTP header, or through third party sites such as DoubleClick.

\begin_layout Quote
The first issue is defining extraneous content: a subjective issue dependent
 on individual users or groups of users.
 There is a consensus on what 
\emph on
kinds
\emph default
 of content may generally be viewed as extraneous and this undesirable from
 the viewpoint of latency.
 Advertisements and resources that are placed on a user's site solely for
 the purpose of gathering user/specific data, i.e., content extraneous to
 the core content of the page, could be considered undesirable.
 Pop-up and pop-under windows are annoyances that modern browsers often
 suppress.

The midday results show a 57% reduction in the number of servers accessed
 when Adblock is enabled.
 There is a 27% reduction both in number of objects retrieved and number
 of bytes downloaded with Adblock enabled.
 The other timeframes show similar results for the recution in servers,
 objects and bytes.

The last column of Table 5 shows a how these differences translate into
 median download latency reductions.
 We see a 33% median reduction across the three time periods - consistent
 with both mean (27-37%) and 90th percentile (28-46%) figures (not shown
 in Table 5).
 The latency results are expected given the significant reduction in the
 number of servers contacted and the number of objects and bytes downloaded.
