Abstract: A content item generation system which implements techniques for selecting and identifying content items to return in response to a request is described. For example, the content item generation system may separate requirements included with a request into first and second sets of requirements. The first set of requirements may be used to identify which content items or content item campaigns may be suitable to respond to the request. The second set of requirements may be used to determine whether items associated with the selected content items or content item campaigns correspond to technical requirements specified in the request.

Abstract: A media item cache manager system which implements techniques for efficiently using cache memory to respond to requests. The cache memory may include information on items along with a status indicator for each of the items, indicating different status information. Some examples of possible status indicators include valid, invalid, or in-progress indicators.

Abstract: A request filtration system that implements techniques to reduce load on a downstream service by efficiently filtering requests before they are processed by the downstream service. The request filtration system may be used by a request processing system to eliminate requests that satisfy any of one or more filters. For example, each filter specifies one or more attributes that may apply to one or more requests. If a request satisfies a filter, then the request is not considered by the downstream service or a content item does not need to be selected by the request processing system in response to the request.

Abstract: A system and method are provided for automatically selecting one of multiple formats in which to serve a content item. The system collects data regarding content items served and user activity and/or revenue regarding those served items. These data are used to calculate performance values or scores of each format for specified factors such as destination (e.g., a web domain, a URL, a content channel), visibility (e.g., above the fold), a period of time, a vertical or type of content, and so on. When a new content request is received, the format selected for serving in response to the request is chosen based on the competing formats' calculated performances, and a suitable content item is selected. The selected format may be the format likely to generate the most revenue, may be selected by statistical sampling, or may be selected by using the performance values/scores in some other way.

Abstract: Creating the illusion of a larger diamond from smaller diamonds. In an embodiment, four corner diamonds (of circular shape and equal size) are placed in four corners of a square area and a center diamond is placed in the gap presented by the four corner diamonds. The center diamond is placed at a level below that of the four corner diamonds and is supported by a rim such that the center diamond does not have to rely on the corner diamonds for support. The rim supports the center diamond at about 90-95% of its pavilion height in one embodiment. Prongs are used in addition to support the corner diamonds.

Abstract: A method for configuring a device's interaction with an application without using cookies. The method includes entering information that needs to be used each time a transaction with an application residing on an application server is performed and storing the information at the application server. The method also includes initiating the transaction between the device and the application server, and looking up based on a user indicator an automatic entry indicator. The then includes sending from the application server the information when the automatic entry indicator is indicative of automatic entry having been enabled.
