Why does the Options attribute in the apache configuration file fail to achieve the expected results?

Article Title: Why does the Options attribute in the apache configuration file fail to achieve the expected results. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Problem Analysis: The Options attribute has a very special function: if you do not use "+" or "-" to add or remove a function, all features of each previously defined Options will be canceled until you specify some features for it. The options attribute is irrelevant to the overall setting and the virtual host setting, and does not work with each other because they are overloaded within a specific range.
Solution: If you want to use the Options settings in the overall settings in the VM, do not specify the Options attribute in the VM settings. To add or remove features, use the "+" or "-" symbol. For example:
Options shortdes ExecCGI

Options Indexes

The Options attributes of the overall settings are Des and ExecCGI, while the Options attributes in the/www/htdosc directory are only Indexes. To enable the/www/htdocs directory to have the attributes of the pair Des, ExecCGI, and Indexes, you can also use the following method:
Options shortdes ExecCGI

Options + Indexes
