In one embodiment, a method includes sending a first request comprising an http-header that includes one or more http-header fields for a webpage from a first user to a computing server, receiving a second request for access to a first information associated with the mobile-client system from the computing server in response to the first request, wherein the first information comprises one or more user-profile fields associated with a user profile of the first user, sending the first information responsive to the second request to the computing server, and receiving the requested webpage customized based on one or more determined attributes of the mobile-client system from the computing server, the one or more attributes being determined based on a comparison between the one or more http-header fields and the one or more user-profile fields with a database comprising attributes of a plurality of types of mobile-client systems.

Detecting mobile device attributes

A computer-implemented method for customizing network detection results may include identifying a connection between a client device and a frontend server of a web-based computing system. The method may also include obtaining at least one criterion for customizing a network-carrier analysis of the connection for use by a backend application of the web-based computing system. In addition, the method may include performing, based on the criterion, the customized network-carrier analysis of the connection to create a customized report of network-carrier information about the connection. Furthermore, the method may include providing the customized report of network-carrier information to the backend application. Finally, the method may include performing, based on the customized report, at least one task associated with improving a function of the web-based computing system. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for customizing network detection results

In one embodiment, a method includes sending a request to a computing server from a mobile-client system for a multimedia object. The mobile-client system receives, from the computing server, a query in response to the request for SIM-card information of the mobile-client system. The mobile-client system executes an application in response to the query to access a SIM card of the mobile-client system and retrieve SIM-card information. The mobile-client system sends the retrieved SIM-card information to the computing server. The mobile-client system receives a multimedia object from the computing server, the multimedia object being customized based on the retrieved SIM-card information.

Detecting carriers for mobile devices

In one embodiment, a method includes receiving a request for a webpage from a mobile-client system of a user, where the request includes an http-header, accessing information describing the user, determining the attributes of the mobile-client system based on the http-header and the information describing the user, and transmitting the webpage to the mobile-client system in response to the request, where the webpage has been customized based on the determined attributes of the mobile-client system.

The embodiments are related to a log framework for controlling data sampling at client devices based on a lifecycle of a product. A product can be an application executing on a client device and/or a feature of the application. The sampling of data depends on a lifecycle of the product. For example, data may be sampled at a higher rate during a launch phase of the product, e.g., as more data may be required to analyze the behavior of the product, and then may be decreased to a lower rate when the product matures. Similarly, for a product that is in an experiment phase for a specified duration, data may be logged during the experiment phase, e.g., at a constant sampling rate, and then the logging may be terminated at the expiry of the experiment phase, thereby saving resources, e.g., processing capacity, storage capacity of the client device.

Controlling data logging based on a lifecycle of a product

In one embodiment, a method includes receiving a request for a multimedia object from a mobile-client system of a first user, wherein the request comprises http-header information of the mobile-client system, determining one or more attributes of the mobile-client system based at least on a social-graph information associated with the first user and the http-header information, wherein determining the one or more attributes comprises calculating a probability score the mobile-client system has the one or more attributes by comparing the social-graph information associated with the first user and the http-header information with a database of a social-networking system, and sending the multimedia object to the mobile-client system in response to the request, the multimedia object being customized based on at least the determined one or more attributes of the mobile-client system.

In one embodiment, a method includes receiving a request for a content object from a mobile-client system of a user, accessing SIM-card information associated with the mobile-client system the user, determining a carrier based at least on the SIM-card information, and sending the webpage to the mobile-client system in response to the request, where the content object has been customized based on the determined carrier of the mobile-client system.
