Embodiment Construction

[0111] The core idea of ​​the present invention is to allocate a resource identifier for the resource address in the intranet server on the SSL VPN gateway device, and establish a corresponding relationship between the resource address in the intranet server and the gateway virtual path represented by the resource identifier. When rewriting the link, the resource identifier is used to replace the corresponding real network path, so as to shorten the link length and speed up the search speed of table items. In addition, the complete link can be sent directly after encoding, and the search for the entry corresponding to the link is only performed when the link is accessed, which avoids wasting time when rewriting the page.

[0112] A kind of link rewriting method based on SSL VPN of the present invention is shown in Figure 3, comprises the following steps:

[0113] Step s301, the SSL VPN gateway receives the link sent by the intranet server to the remote host.

[0114] Step s302,...

Abstract

This invention discloses an OVR method for links based on SSL VPN including the following steps: SSL VPN gateway receives a link sent to a remote host by an internal network server and overwrites the link according to the corresponding relation of the resource address of an internal network server configured locally and a gateway virtual path expressed by the resource ID and sends the link to a remote host. This invention also discloses a SSL VPN gateway device, which applies a resource ID to replace the real network path in a gateway virtual path so that the gateway can get resource ID directly from a request to pick up list index based on the ID so as to speed up looking up and reduces link length effectively by applying virtual path containing resource ID.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to an SSL VPN-based link rewriting method and equipment. Background technique [0002] SSL VPN is a VPN (Virtual Private Network, virtual private network) technology that uses SSL (Security Socket Layer, Secure Socket Layer) encrypted connection to realize remote access. The functions of SSLVPN are shown in Figure 1. Among them, an SSL connection is established between the remote host and the SSL VPN gateway, and the message is transmitted on the Internet in an encrypted manner; while the SSL VPN gateway terminates the SSL connection, and establishes a TCP (Transmission Control Protocol, transmission control protocol) with the server on the intranet. ) connection, transmit the request from the remote host in clear text, and send the server’s response to the remote host through the SSL connection. [0003] The types of URL links on the page include: [0004] (1) Full link...
