Server-Wide Configuration 6i2x5c

Server Identification 6u3371

The ServerTokens directive sets the value of the Server HTTP response header field.

The UseCanonicalPhysicalPort directives are used by the server to determine how to construct self-referential URLs. For example, when a client requests a directory, but does not include the trailing slash in the directory name, httpd must redirect the client to the full name including the trailing slash so that the client will correctly resolve relative references in the document.

File Locations 1c6q3k

These directives control the locations of the various files that httpd needs for proper operation. When the pathname used does not begin with a slash (/), the files are located relative to the security tips documentation for more details.

Limiting Resource Usage 495m3j

The LimitRequest* directives are used to place limits on the amount of resources httpd will use in reading requests from clients. By limiting these values, some kinds of denial of service attacks can be mitigated.

The RLimit* directives are used to limit the amount of resources which can be used by processes forked off from the httpd children. In particular, this will control resources used by CGI scripts and SSI exec commands.

The ThreadStackSize directive is used with some platforms to control the stack size.

Implementation Choices 661p1c

The Mutex directive can be used to change the underlying implementation used for mutexes, in order to relieve functional or performance problems with APR's default choice.
