A control method of http data flow based on linux platform

Abstract

The invention relates to the field for monitoring and controlling the network communication through a network access device, and in particular relates to a hyper text transport protocol (HTTP) data flow control method based on a linux platform. The method comprises the following steps of detecting whether the HTTP kernel detection module is forbidden or not at the moment; detecting whether a message received from a network interface is a HTTP request message or not; extracting a request uniform resource locator (URL) address of the current HTTP request message, and comparing the extracted request URL address with the content configured by a user to filter the URL address; when the request URL address conforms to a filter rule, resetting a transmission control protocol (TCP) head, arranging fin at 1, exchanging a multi-access computer (MAC) address and an internet protocol (IP) address as well as a source port and a target port, deleting the HTTP content of an application layer, and recalculating characteristics of the data message such as a TCP sequence number. The control method has wide application range, is convenient to implement and has a positive effect on improving the internet surfing environment and purifying the network information content; and only a filter or reoriented condition in a character string form only needs to be provided on the aspect of the configuration, and a good application effect can be realized even under the background that the user does not have corresponding professional knowledge.

Description

technical field [0001] The invention relates to the field of monitoring and controlling network communication by network access equipment, in particular to a method for controlling HTTP data flow based on a linux platform. Background technique [0002] The HTTP protocol (hypertexttransportprotocol) is a data transfer protocol that specifies the rules for mutual communication between the browser and the World Wide Web server, and transmits World Wide Web documents through the Internet. It allows the transfer of Hypertext Markup Language (HTML) documents from a web server to a web browser. HTML is a markup language used to create documents that contain links to related information. The protocol initiator can click a link to access other documents, images or multimedia objects, and obtain additional information about the link item. HTTP works on the TCP protocol in the TCP / IP protocol system. HTTP / 1.1 is currently used in the WWW, which was formulated in June 1990 by RFCs (Re...
