Detecting mobile device attributes

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• send, to a computing server, a first request for a webpage from a first user, the first request comprising an http-header, wherein the http-header comprises one or more http-header fields comprising information associated with a browser application installed on the mobile-client system;
• receive, from the computing server, in response to the first request, a second request for access to a first information associated with the mobile-client system, wherein the first information comprises one or more user-profile fields associated with a user profile of the first user and one or more other fields comprising information associated with one or more other applications installed on the mobile-client system;
• send, to the computing server responsive to the second request, the first information comprising the one or more user-profile fields associated with the user profile of the first user and the one or more other fields comprising the information associated with the one or more other applications installed on the mobile-client system;
• and
• receive, from the computing server, the requested webpage, wherein the webpage is customized based on one or more determined device attributes of the mobile-client system, the one or more device attributes being determined based on (1) a comparison between the one or more http-header fields and the one or more user-profile fields with a database comprising device attributes of a plurality of types of mobile-client systems, and (2) the one or more other fields comprising information associated with the one or more other applications installed on the mobile-client system, and (3) a prediction determination made based on social-networking information of the first user.

A system comprising:

• one or more processors;
• and a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• send, to a computing server, a first request for a webpage from a first user, the first request comprising an http-header, wherein the http-header comprises one or more http-header fields comprising information associated with a browser application installed on the mobile-client system;
• receive, from the computing server, in response to the first request, a second request for access to a first information associated with the mobile-client system, wherein the first information comprises one or more user-profile fields associated with a user profile of the first user and one or more other fields comprising information associated with one or more other applications installed on the mobile-client system;
• send, to the computing server responsive to the second request, the first information comprising the one or more user-profile fields associated with the user profile of the first user and the one or more other fields comprising the information associated with the one or more other applications installed on the mobile-client system;
• and
• receive, from the computing server, the requested webpage, wherein the webpage is customized based on one or more determined device attributes of the mobile-client system, the one or more device attributes being determined based on (1) a comparison between the one or more http-header fields and the one or more user-profile fields with a database comprising device attributes of a plurality of types of mobile-client systems, and (2) the one or more other fields comprising information associated with the one or more other applications installed on the mobile-client system, and (3) a prediction determination made based on social-networking information of the first user.
