KeepAliveTimeout directive
Syntax: KeepAliveTimeout seconds
Default: KeepAliveTimeout 15
Context: server config
Status: Core
Compatibility: KeepAliveTimeout is only available in Apache 1.1 and later.
The number of seconds Apache will wait for a subsequent request before closing the connection. Once a request has been received, the timeout value specified by the Timeout directive applies.

<Limit> directive
Syntax: <Limit method method ... > ... </Limit>
Context: any
Status: core
Access controls are normally effective for all access methods, and this is the usual desired behaviour. In the general case, access control directives should not be placed within a <limit> section.

The purpose of the <Limit> directive is to restrict the effect of the access controls to the nominated HTTP methods. For all other methods, the access restrictions that are enclosed in the <Limit> bracket will have no effect. The following example applies the access control only to the methods POST, PUT, and DELETE, leaving all other methods unprotected:

<Limit POST PUT DELETE>
require valid-user
</Limit>
The method names listed can be one or more of: GET, POST, PUT, DELETE, CONNECT, OPTIONS, TRACE, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK. The method name is case-sensitive. If GET is used it will also restrict HEAD requests.

<LimitExcept> directive
Syntax: <LimitExcept method method ... > ... </LimitExcept>
Context: any
Status: core
Compatibility: Available in Apache 1.3.5 and later
<LimitExcept> and </LimitExcept> are used to enclose a group of access control directives which will then apply to any HTTP access method not listed in the arguments; i.e., it is the opposite of a <Limit> section and can be used to control both standard and nonstandard/unrecognized methods. See the documentation for <Limit> for more details.

LimitRequestBody directive
Syntax: LimitRequestBody number
Default: LimitRequestBody 0
Context: server config, virtual host, directory, .htaccess
Status: core
Compatibility: LimitRequestBody is only available in Apache 1.3.2 and later.
Number is a long integer from 0 (meaning unlimited) to 2147483647 (2GB). The default value is defined by the compile-time constant DEFAULT_LIMIT_REQUEST_BODY (0 as distributed).

The LimitRequestBody directive allows the user to set a limit on the allowed size of an HTTP request message body within the context in which the directive is given (server, per-directory, per-file or per-location). If the client request exceeds that limit, the server will return an error response instead of servicing the request. The size of a normal request message body will vary greatly depending on the nature of the resource and the methods allowed on that resource. CGI scripts typically use the message body for passing form information to the server. Implementations of the PUT method will require a value at least as large as any representation that the server wishes to accept for that resource.

This directive gives the server administrator greater control over abnormal client request behavior, which may be useful for avoiding some forms of denial-of-service attacks.
