Abstract: Techniques for verifying the transfer from a content provider of a selected data file selected by a client device using a proxy server is disclosed. By creating a local set of characteristics of the selected data file, network traffic sent between the client device and the content provider can be monitored. A local record of a transfer session is then created, and a download request from the client device is received and forwarded, thus initiating the transfer of the selected data file to the content provider. A data file is then received from the content provider and forwarded to the client device. The characteristics of the received data file are evaluated, thus allowing verification that the characteristics of the received data file match the local set of characteristics of the selected data file to take place. Finally, the received data file is forwarded to the client device.

Abstract: Apparatus and methods are provided for identifying the physical location of internet service providers. Requests for data are received from a plurality of locatable browsing clients that include the IP address of the internet service provider that each of the locatable browsing clients is connected to, and geolocation data identifying the physical location of each of the plurality of locatable browsing clients. These requests are stored in records in a first database. A query is then performed on the first database to identify records where the originating IP addresses match and the geolocation data match within a threshold range; the results of the query are then stored in records in a second database. The records in the second database can then be used to provide location-specific data to clients in a web server implementation, or make bids on advertising opportunities based upon a browsing client's location.
