Exploring the HTTP core module directives
At each of the three levels (the blocks discussed previously), directives can be inserted in order to affect the behavior of the web server. The following subsections cover all directives that are introduced by the main HTTP module, grouped thematically. For each directive, an indication regarding the context is given. Some cannot be used at certain levels. For instance, it would make no sense to insert a server_name directive at the http block level, since server_name is a directive directly affecting a virtual host—it should only be inserted in the server block. To that extent, the table indicates the possible levels where each directive is allowed—the http block, the server block, the location block, and, additionally, the if block.
Note
This documentation is valid as of Stable version 1.25. Future updates may alter the syntax of some directives or provide new features that are not discussed here.
