First, let's review the principles and processes of Web containers calling servlet, and then explain the principles of filter interception, filter class and fiterchain class. Register and run the filter. Write a practical case: Use filter to implement centralized resource ac

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.

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
