UNIX-based Web server Security Guide One. Security vulnerabilities Vulnerabilities on Web servers can be considered in the following ways: 1. Secret files, directories, or important data that you do not have access to on a Web server. 2. When sending information to the server from a remote user, especially when something like a credit card, it is illegally int

vulnerabilities, are constantly updated in the version upgrade process, this is not listed. Three. Consider security from a CGI programming perspective. 1. It is safer to use a compiled language than to interpret the language, and the CGI program should be placed under Cgi-bin independent of the HTML repository, in order to prevent some illegal visitors from obtaining the original code of an interpreted language from the browser and looking for a l

In addition, many Web servers themselves have some security vulnerabilities, are constantly updated in the version upgrade process, this is not listed. Third, from the CGI programming perspective to consider security. 1. It is safer to use a compiled language than to inter

, Table. getn (mytable) Do Print (mytable [Index]) End Table. Sort (mytable) This simple function traverses the entire table and rearrange it from small to large. 6.2. Table. insert (mytable, positon, value) Table. the insert function inserts a new value in Table China. The location parameter is optional. If no value is set, a new value is added to the end of table A. If this value is specified, it is inserted to the specified position. Table. insert (mttable, 25, "hello ") 6.3.

Chapter III Structure and CASCADE1. When determining which values should be applied to an element, the user agent not only takes into account the inheritance, but also considers the specificity of the declaration, and also the origin of the declaration itself, which is called Cascading. 、2, Particularity. If an element has two or more conflicting attribute declarations, the Highest-specificity declaration wins. For the value of the attribute of each ID given in the selector, add 0,1,0,0;
