  • Split-tunneling for clientless SSL-VPN sessions with zero-configuration
    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.

  • Systems and methods for a unique mechanism of providing ‘clientless SSLVPN’ access to a variety of web-applications through a SSLVPN gateway
    Patent number: 10484336
    Abstract: The present disclosure is directed towards systems and methods for rewriting a HTTP response transmitted via a clientless SSL VPN session. An intermediary device may identify, in a HTTP response transmitted via a clientless SSL VPN session, an absolute URL that includes a first hostname of the server. The device may provide a unique string corresponding to the first hostname of the server. The device may generate a URL segment by combining the unique string with a second hostname of the device. The device may rewrite the absolute URL by replacing the first hostname in the absolute URL with the generated URL segment. A domain name system (DNS) server for the client may be configured with a DNS entry comprising a wildcard combined with the second hostname, to cause the DNS server to resolve the rewritten absolute URL to an IP address of the device.
