Abstract: A DNS name server manages CNAME records. The server receives a query for a first Address record for a fully qualified domain name from a requester. The server determines that the fully qualified domain name has a CNAME record, where the fully qualified domain name is a root domain. The server traverses a chain according to the CNAME record to locate a second Address record that includes an IP address. The server generates a response to the query that includes a third Address record for the fully qualified domain name that includes at least the IP address of the located second Address record. The server transmits the generated response to the requester.

Abstract: A proxy server receives from a client device a request for a network resource hosted at an origins server for a domain. The request is received at the proxy server as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains and resolve to the proxy server and are owned by different entities. The proxy server requests the network resource from the origin server. The proxy server receives a response from the origin server that indicates that the network resource is unavailable. The proxy server transmits a custom error page to the client device that indicates that the requested resource is unavailable.

Abstract: A first packet of a first protocol version type that includes an incoming request for an action to be performed on an identified resource is received from a client at a proxy server as a result of a DNS request resolving to a network address of the proxy server. The proxy server transmits an outgoing request for the action to be performed on the identified resource to a network address of the destination origin server in a second packet that is of the second protocol version type. The proxy server receives a third packet that includes an incoming response from the destination origin server, the third packet being of the second protocol version type. The proxy server transmits a fourth packet to the client, the fourth packet being of the first protocol version type, wherein the fourth packet includes an outgoing response that is based on the incoming response.

Abstract: A proxy server receives, from multiple visitors of multiple client devices, a plurality of requests for actions to be performed on identified network resources belonging to a plurality of origin servers. At least some of the origin servers belong to different domains and are owned by different entities. The proxy server and the origin servers are also owned by different entities. The proxy server analyzes each request it receives to determine whether that request poses a threat and whether the visitor belonging to the request poses a threat. The proxy server blocks those requests from visitors that pose a threat or in which the request itself poses a threat. The proxy server transmits the requests that are not a threat and is from a visitor that is not a threat to the appropriate origin server.

Abstract: A proxy server automatically includes web applications in web pages at the network level. The proxy server receives, from a client device, a request for a network resource at a domain and is hosted at an origin server. The proxy server retrieves the requested network resource. The retrieved network resource does not include the web applications. The proxy server determines that the web applications are to be installed within the network resource. The proxy server automatically modifies the retrieved network resource to include the web applications. The proxy server transmits a response to the client device that includes the modified network resource. The network resource may remain unchanged at the origin server.

Abstract: A proxy server in a cloud-based proxy service receives a secure session request from a client device as a result of a Domain Name System (DNS) request for a domain resolving to the proxy server. The proxy server participates in a secure session negotiation with the client device including transmitting a digital certificate to the client device that is bound to domain and multiple other domains. The proxy server receives an encrypted request from the client device for an action to be performed on a resource that is hosted at an origin server corresponding to the domain. The proxy server decrypts the request and participates in a secure session negotiation with the origin server including receiving a digital certificate from the origin server. The proxy server encrypts the decrypted request using the digital certificate from the origin server and transmits the encrypted request to the origin server.

Abstract: A method and apparatus for managing CNAME records such that CNAME records at the root domain are supported while complying with the RFC specification (an IP address is returned for any Address query for the root record). The authoritative DNS infrastructure acts as a DNS resolver where if there is a CNAME at the root record, rather than returning that record directly, a recursive lookup is used to follow the CNAME chain until an A record is located. The address associated with the A record is then returned. This effectively “flattens” the CNAME chain. This complies with the requirements of the DNS specification and is invisible to any service that interacts with the DNS server.

Abstract: The present disclosure provides systems and methods to increase resolution of imagery. In one example embodiment, a computer-implemented method includes obtaining a current low-resolution image frame. The method includes obtaining a previous estimated high-resolution image frame, the previous estimated high-resolution frame being a high-resolution estimate of a previous low-resolution image frame. The method includes warping the previous estimated high-resolution image frame based on the current low-resolution image frame. The method includes inputting the warped previous estimated high-resolution image frame and the current low-resolution image frame into a machine-learned frame estimation model. The method includes receiving a current estimated high-resolution image frame as an output of the machine-learned frame estimation model, the current estimated high-resolution image frame being a high-resolution estimate of the current low-resolution image frame.

Abstract: A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The request is received at the proxy server as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains that resolve to the proxy server and are owned by different entities. The proxy server transmits the request to the origin server. Responsive to determining that the origin server is offline, the proxy server determines whether the requested resource is available in cache. If it is in cache, the proxy server retrieves the requested resource from the cache and transmits the requested resource to the client device.

Abstract: When a user sees a content item presented by a social networking system, the user may select an option to save the content item. The saved content item may be reinserted in a newsfeed presented to the user, integrated into collections, archived, used for notifications to the user, or otherwise subsequently presented to the user. A plug-in may be used to save content items accessed through websites external to the social networking system. As privacy settings associated with a saved content item are modified, the modified privacy settings are applied to the saved content item, which may prevent the user saving the content item from subsequently viewing the saved content item.

Abstract: A proxy server in a cloud-based proxy service receives a message that indicates that a domain, whose traffic passes through the proxy server, may be under a denial-of-service (DoS) attack. The proxy server enables a rule for the domain that specifies that future requests for resources at that domain are subject to at least initially passing a set of one or more challenges. In response to receiving a request for a resource of that domain from a visitor, the proxy server presents the set of challenges that, if not passed, are an indication that that the visitor is part of the DoS attack. If the set of challenges are passed, the request may be processed. If the set of challenges are not passed, the request may be dropped.

Abstract: A proxy server for limiting Internet connection speed of visitors that pose a threat. The proxy server receives from a client device a request to perform an action on an identified resource that is hosted at an origin server for a domain. The proxy server analyzes the request to determine whether a visitor belonging to the request poses a threat. If the proxy server determines that the visitor poses a threat, the proxy server reduces the speed at which the proxy server processes the request while keeping a connection to the client device open.

Abstract: A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session with. The server transmits the encrypted premaster secret to the different server for decryption along with other information necessary to compute a master secret. The different server decrypts the encrypted premaster secret, generates the master secret, and transmits the master secret to the server. The server receives the master secret and continues with the handshake procedure including generating one or more session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server.
