  • Patent number: 11533289
    Abstract: Described embodiments provide systems and methods for rewriting an URL in a message transmitted via a clientless SSL VPN session. An intermediary device may identify, in a HTTP response transmitted via the session, an absolute URL that includes a hostname of the server. The device may determine that the absolute URL includes an intranet domain name. The device may generate, responsive to the determination, a URL segment by combining a unique string corresponding to the hostname of the server, with a hostname of the device. The device may rewrite, responsive to the determination, the absolute URL by replacing the server hostname in the absolute URL with the generated URL segment. A DNS server for the client may be configured with a DNS entry comprising a wildcard combined with the device hostname, to cause the DNS server to resolve the rewritten absolute URL to an IP address of the device.

  • Patent number: 11528320
    Abstract: Described herein are systems and methods for end user connection load balancing amongst multiple on-premise connector proxies deployed across geographic locations and reducing connection setup latency without using a shared or distributed database. The system can load balance connections deterministically amongst the on-premise connector proxies using load statistics. The system utilizes an intelligent DNS service that can use network experience data, service availability, and application metrics to provide sophisticated traffic management via DNS or API-based decisions. The system can include a domain name system (DNS) resolver configured to receive metrics for a first connector and a second connector of a data center of an entity, receive a DNS request including an entity identifier and a data center identifier; and transmit a response to the DNS request identifying a server selected based on the metrics identified using the entity identifier and the data center identifier.

  • Patent number: 11522847
    Abstract: Aspects described herein relate to methods, devices and systems that allow for a client device, as part of a remote access or cloud-based network environment, to map external user identities to desktops and applications. Local user accounts can be dynamically generated on a virtual delivery agent. A mapping of the local user account to an external identity can be secured using signed tokens and maintained by a broker machine that allocates resources for the deployment of particular applications to the client device from the virtual delivery agent. This allows for the removal of any dependency on an Active Directory for maintaining user identities or federated sign-on services, greatly simplifying the management of user identities within the system and allowing for greater compatibility across client devices.
