example 1

[0051] Example 1: For Deep Content Inspection

[0052] Some implementations can detect the content of text, and then other file types can be glued; some implementations may go deeper, such as detecting office files. Then other than text and office files can be glued.

example 2

[0053] Example 2: Gateway Antivirus

[0054] Because virus matching is a CPU-intensive task, the performance of general gateway antivirus products is weak, which may be an order of magnitude worse than that of switching and routing devices.

[0055] In order to improve the availability of gateway antivirus products, product developers can selectively scan part of the traffic. For example, scan files (exe, pictures, scripts, etc.) that are most likely to be infected with viruses. Other file types can be glued.

[0056] For products based on file killing, it is impossible to restore files of any size due to the limited memory of the device. Therefore, when the file size Content-Length field exceeds the threshold, you can set the glue condition.

[0057] Specifically, the present invention provides a core-level TCP connection bonding method for accelerating application proxy, such as Figure 4 As shown, it specifically includes the following steps:

[0058] Step S401, the pr...

Abstract

The invention discloses a core-level TCP adhering junction method for accelerating an application proxy, which comprises the following steps: a proxy server establishes a TCP connection with a server after receiving a http request message sent by a client which establishes the TCP connection with the proxy server, and forwards the http request message to the server; and the server transmits a http response-header message to the proxy server, a adhering module detects whether the http response-header message meets the pre-configured adhering conditions when the http response-header message is transmitted to a kernel-mode IP protocol stack, if so, a TCP adhering junction operation is carried out. The method enlarges the application range of the TCP adhering technology.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a core-level TCP connection bonding method for accelerating application agents. Background technique [0002] Application-level proxy is widely used in HTTP proxy, HTTP cache, application-based load balancing, deep content inspection, gateway virus filtering and other fields, and plays an important role in network services today. Statistics show that more and more Internet security problems come from the application layer, and application-level proxies will play an increasingly important role in the future. [0003] Traditional application-level proxies use application-layer connection glue proxies, such as figure 1 As shown, the application proxy sits between the client and the server being accessed. For the client, the proxy acts as a server, and for the server, the proxy acts as a client. The client first establishes a socket connection with the agent, and then the...
