websense web filter

1, filter is used to intercept user requests, before the server responds, you can modify the request and response after interception, so that many developers want to achieve the function.2.

When it comes to displaying ads on a Web page, the little one thinks it's not a bad thing. But why write such a piece of teaching? Small series can accept web ads, provided that it does not affect the normal browsing of the page can be. But now a lot of websites show ads have been far beyond the scope of our tolerance, floating around, play window, even if you click on the link to the page when you have to

This article describes txt2html, a common domain work project created by David, to illustrate Python's programming skills. Txt2html is a web-based Filter agent-a program that reads web-based documents for a user and then displays the modified pages to the user's browser. To make this possible, txt2html runs as a CGI program, querying the information of external

Take the post method as an example. For example, the UserInfo. aspx page filters all parameters on the Email, ICQ, and QQ pages by default. Step.4 generate Xml fixed text on the configuration category page. In order to reduce the complexity of the master site, and each application site can flexibly expand its own fea

The server invokes its service method for request processing, and the service method calls Doget,dopost, respectively, based on the requested type. 2. Thread is unsafe because it is a singleton mode 3. The custom servlet inherits the HttpServlet and overrides the corresponding Doget methods. The method in the method body cannot cal
